The protein is implicated in phospholipase C signaling and in the production of phosphatidylinositol 3,4,5-trisphosphate (PIP3) by phosphoinositide-3-kinase.[provided by RefSeq, Sep 2009] Expression Ubiquitous expression in brain (RPKM 31.8), thyroid (RPKM 27.9) and 25 other tissues See more Orthologs mouse all
