    Biology, a science of greys

    Models and categories are useful research tools in biology but they do not necessarily represent reality. To better understand life's complexity and avoid pointless controversies, we need to be more aware of their limitations.

    Since its start, synthetic biology has been the subject of intense scrutiny and debate by the public and social scientists. To avoid public resistance and overreaching regulation, the field could learn from how actors in nanotechnology engaged in debate.

    The revival of the extended phenotypeAfter more than 30 years, Dawkins’ Extended Phenotype hypothesis is enriching evolutionary biology and inspiring potential applications
    The revival of the extended phenotype

    After more than 30 years, Dawkins’ Extended Phenotype hypothesis is enriching evolutionary biology and inspiring potential applications

    1. Philip Hunter (ph{at}philiphunter.com)1
    1. 1 London, UK

    When Richard Dawkins proposed the Extended Phenotype hypothesis, it was an interesting addition to explain beaver dams or termite nests. With new technologies and a renewed interest, it is now inspiring research to understand co‐evolution in ecosystems and applications in agriculture and conservation.

    Engagement of αvβ3‐integrin with fibronectin at mature focal adhesions localises an Rcc2/Anxa2/Rac1 containing complex to these sites, preventing Rac1 from stabilising microtubules. When αvβ3 is not present, the complex associates with α5β1‐integrin instead, resulting in increased microtubule stability.

    Rhino recruits Deadlock through a novel interacting mode that is crucial to piRNA biogenesis and transposon silencing. Key amino acid differences determine the cross‐species incompatibility between Drosophila melanogaster and Drosophila simulans.

    Synopsis

    Rhino recruits Deadlock through a novel interacting mode that is crucial to piRNA biogenesis and transposon silencing. Key amino acid differences determine the cross‐species incompatibility between Drosophila melanogaster and Drosophila simulans.

    • The crystal structures of Rhino‐Deadlock complex from melanogaster and simulans indicate that one Rhino CSD domain binds the HhH motif of one Deadlock through a novel interface.

    • Disrupting the interface leads to infertility and transposon hyperactivation in flies, indicating the crucial role of Rhino‐Deadlock machinery in piRNA biogenesis.

    • The structures highlight that the cross‐species incompatibility is due to electrostatic repulsion caused by amino acid differences between the two species.

    The CRISPR4‐Cas system of the Streptococcus thermophilus spacer integration complex contains the Cas2‐DnaQ fusion protein. This study shows that the DnaQ domain is required for the processing of the protospacers prior to integration into the CRISPR array.

    Synopsis

    The CRISPR4‐Cas system of the Streptococcus thermophilus spacer integration complex contains the Cas2‐DnaQ fusion protein. This study shows that the DnaQ domain is required for the processing of the protospacers prior to integration into the CRISPR array.

    • The DnaQ domain fused to Cas2 in the S. thermophilus CRISPR4‐Cas system is a 3′–5′ exonuclease.

    • The DnaQ domain in the Cas1:Cas2‐DnaQ complex trims 3′ ends of protospacers to generate overhangs optimal for integration.

    • Cas1:Cas2‐DnaQ integrates trimmed protospacers into the CRISPR array.

    The endoplasmic reticulum (ER) makes physical contacts with most cellular organelles. This study identifies MOSPD2 as a new ER‐anchored receptor, which binds FFAT‐motif containing proteins in other organelles such as Golgi, endosomes and mitochondria.

    Synopsis

    The endoplasmic reticulum (ER) makes physical contacts with most cellular organelles. MOSPD2 (motile sperm domain‐containing protein 2) is a new ER‐anchored receptor, which binds FFAT (two phenylalanines in an acidic track)‐motif containing proteins. Analogous to vesicle‐associated membrane protein‐associated protein (VAP)‐A and VAP‐B, MOSPD2 mediates the formation of contact sites between the ER and a variety of organelles (including endosomes, mitochondria or Golgi).

    • Motile sperm domain‐containing protein 2 (MOSPD2) is a novel ER‐anchored VAP homolog.

    • The FFAT motif is recognized by the Major Sperm Protein (MSP) domain of MOSPD2.

    • MOSPD2 interacts with a variety of organelle (endosomes, mitochondria or Golgi)‐bound proteins and thereby builds membrane contact sites.

    TG2 triggers the trimerization and activation of HSF1 dependent on its disulphide isomerase activity. The inhibition of TG2 restores the unbalance in the HSF1‐HSP70 pathway in cystic fibrosis indicating a role for TG2 in the regulation of cellular proteostasis under stress.

    Synopsis

    TG2, through its protein disulphide isomerase activity, triggers the trimerization and activation of HSF1. The inhibition of TG2 restores the unbalance in HSF1‐HSP70 pathway in cystic fibrosis indicating that TG2 plays an important role in the regulation of cellular proteostasis under stressful cellular conditions through the modulation of the heat shock response.

    • The protein disulphide activity of TG2 post‐translationally modifies HSF1.

    • TG2, by activating HSF1, regulates HSP70 protein expression.

    MAPKKK3/5 act upstream of MKK4/5 and MPK3/6 in PAMP‐triggered and DAMP‐triggered immunity in plants. The MAPK pathways specified by MAPKKK3/5 and the developmental YDA pathway antagonize by competing for downstream MKKs.

    Synopsis

    MAPKKK3/5 act upstream of MKK4/5 and MPK3/6 in PAMP‐triggered and DAMP‐triggered immunity in plants. The MAPK pathways specified by MAPKKK3/5 and the developmental YDA pathway antagonize by competing for downstream MKKs.

    • MAPKKK3/5, MKK4/5 and MPK3/6 form a MAPK cascade to transduce defence signals in PTI.

    • Developmental defects caused by silencing YDA are suppressed in the mapkkk3/5 double mutant.

    • Loss of YDA leads to increased PAMP‐induced activation of MPK3/MPK6.

    • Brassinosteroid has an inhibitory effect on PAMP‐induced MAPK activation.

    Aβ1–42 triggers translation of axonal mRNAs whose protein products form signaling complexes that transmit the presence of Aβ1–42 from the cellular periphery back to the neuronal soma.

    Synopsis

    Aβ1–42 triggers translation of axonal mRNAs whose protein products form signaling complexes that transmit the presence of Aβ1–42 from the cellular periphery back to the neuronal soma.

    • Translation of pre‐localized sentinel mRNAs is an immediate response mechanism of axons to Aβ1–42.

    • Axonal protein synthesis generates a retrograde signaling complex that transmits the information regarding the insult to the cell body.

    • Axonal production of vimentin is required for the retrograde signaling complex.

    Microtubule‐associated proteins Map7/7D1/Ensconsin and Dishevelled form an evolutionarily conserved axis in β‐catenin‐independent Wnt signaling and/or PCP formation.

    Synopsis

    Microtubule‐associated proteins Map7/7D1/Ens and Dishevelled form an evolutionarily conserved axis in β‐catenin‐independent Wnt signaling and/or PCP formation.

    • Map7/7D1 cooperate with a Kinesin‐1 Kif5b to coordinate Dishevelled dynamics and microtubule remodeling in the Wnt5a signaling pathway.

    • Map7/7D1 and their fly homolog Ens show planar‐polarized distribution in both mouse and fly epithelia.

    • Ens is required for polarized localization of Dishevelled during PCP formation in pupal wing epithelia.

    • Map7/7D1/Ens play an evolutionarily conserved role in Dishevelled localization.

    The topoisomerase poison camptothecin (CPT) induces fork reversal, which is thought to stabilize replication forks. Here, yeast Tel1, orthologue of human ATM, protects CPT‐induced reversed forks from nucleolytic degradation by the MRX complex.

    Synopsis

    The topoisomerase poison camptothecin (CPT) induces fork reversal, which is thought to stabilize replication forks. Here, yeast Tel1, orthologue of human ATM, protects CPT‐induced reversed forks from nucleolytic degradation by the MRX complex.

    • The absence of Tel1 or its kinase activity causes a specific hypersensitivity to CPT and decreases fork reversal in CPT.

    • The decreased reversed fork levels in the absence of Tel1 are due to unscheduled nucleolytic processing that depends mainly on Mre11 nuclease activity.

    • Tel1 function in reversed fork stabilization becomes dispensable when fork reversal is prevented by the lack of the replisome‐associated factor Mrc1, whose absence also relieves the hypersensitivity to CPT of tel1Δ cells.
