| + | [https://www.uniprot.org/uniprot/PIPA_DROME PIPA_DROME] The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes (By similarity). Essential component of the phototransduction pathway (PubMed:2457447). Essential downstream component of a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; required for the activation of Cad99C and consequently Cad99C-dependent endosome formation, which is essential for the Duox-dependent production of reactive oxygen species (ROS) in response to intestinal bacterial infection (PubMed:25639794).[UniProtKB:Q9P212]<ref>PMID:2457447</ref> <ref>PMID:25639794</ref> | ||

| + | INAD assembles key enzymes of the Drosophila compound eye photo-transduction pathway into a supramolecular complex, supporting efficient and fast light signaling. However, the molecular mechanism that governs the interaction between INAD and NORPA (phospholipase Cbeta, PLCbeta), a key step for the fast kinetics of the light signaling, is not known. Here, we show that the NORPA C-terminal coiled-coil domain and PDZ-binding motif (CC-PBM) synergistically bind to INAD PDZ45 tandem with an unexpected mode and unprecedented high affinity. Guided by the structure of the INAD-NORPA complex, we discover that INADL is probably a mammalian counterpart of INAD. The INADL PDZ89 tandem specifically binds to PLCbeta4 with a mode that is strikingly similar to that of the INAD-NORPA complex, as revealed by the structure of the INADL PDZ89-PLCbeta4 CC-PBM complex. Therefore, our study suggests that the highly specific PDZ tandem - PLCbeta interactions are an evolutionarily conserved mechanism in PLCbeta signaling in the animal kingdom. | ||
