UniProt Contributed Function Data
Has a role in growth of the perineurial glial layer of the larval peripheral nerve (PubMed:27552662). May have a role in male fertility and eye development or function (PubMed:27552662). Involved in the negative regulation of the Ras/MAPK signaling pathway in the wing by acting with the E2 enzyme Unc6 and the putative E3 ligases Kcmf1 and Ufd4 to mediate the ubiquitination and proteasomal degradation of rl/MAPK (PubMed:27552662).

    Identification: Cam-binding protein that is expressed in the retina.
    The poe gene might affect both neuronal excitability and the transmitter release process.
    Postmeiotic differentiation defect.
    Origin and Etymology
    Discoverer
    Etymology
    The gene is named "pushover" as mutant flies when pushed onto their dorsal surface by mechanical agitation require an average of 46 seconds to right themselves, 20-fold more time than required for wild type.
