Function
Scaffolding protein involved in the regulation of PKA signaling and anchoring to the actin cytoskeleton integrating signals propagated by cAMP, diacylglycerol and calcium (PubMed:10480936, PubMed:10480937, PubMed:12223401). Contributes to the maintenance and regulation of cytoskeletal structures in germline via PKA-mediated signaling (PubMed:12223401). As part of ethanol response in the glia, mediates ethanol-induced structural remodeling of actin cytoskeleton and perineurial membrane topology by anchoring PKA to the membrane of perineurial glia (PubMed:29444420). In specific tissues such as eye and thorax, promotes N/Notch protein stability by inhibiting Cbl-mediated ubiquitination and lysosomal degradation pathway of N/Notch in a PKA-independent way (PubMed:29309414). In the circadian brain neurons evening cells (E-cells), might have a role in circadian pacemaker synchronization by playing a redundant role in signaling downstream of the G protein-couple receptor Pdfr (PubMed:23929551).
