Integrin Beta Pat-3 (pat-3) Caenorhabditis Elegans Recombinant Protein

Integrin alpha ina-1/beta pat-3 is a receptor for laminin. Integrin alpha pat-2/beta pat-3 recognizes the sequence R-G-D in its ligands (Probable). Plays a role in cell migration, morphogenesis and probably in cell-cell interactions (PubMed:19023419, PubMed:17326220, PubMed:23283987). During gonad morphogenesis, involved in distal tip cell (DTC)-mediated guidance of gonad elongation, in maintaining their sharp tapering morphology and in their migration (PubMed:19023419). Involved in the assembly of dense bodies and M lines during body wall muscle embryonic development by recruiting one of their components, cpna-1, to integrin-mediated attachment sites (PubMed:23283987). May play a similar role in the assembly of dense bodies in gonadal myoepithelial sheath cells (PubMed:17326220). Probably by acting as a receptor for apoptotic cells, plays a role in the clearance of apoptotic cells during mid-embryogenesis (PubMed:20226672). Required for ovulation (PubMed:17326220). Dephosphorylated, probably within the alpha pat-2/beta pat-3 integrin receptor complex, by the phosphatase dep-1, which leads to down-stream effects including the negative regulation of let-23 signaling and vulval induction (PubMed:28135265). When unphosphosphorylated, recruits the cytoplasmic adapter protein tln-1 to the plasma membrane of secondary vulval precursor cells (PubMed:28135265). This promotes the linking of focal adhesion sites to the F-actin cytoskeleton, and it also acts to restrict the mobility of the let-23 receptor on the plasma membrane of vulval cells which thereby attenuates let-23 signaling (PubMed:28135265).
