[[ | [[https://www.uniprot.org/uniprot/RB27A_MOUSE RB27A_MOUSE]] Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse (By similarity). [[https://www.uniprot.org/uniprot/SYTL2_HUMAN SYTL2_HUMAN]] Isoform 1 acts as a RAB27A effector protein and plays a role in cytotoxic granule exocytosis in lymphocytes. It is required for cytotoxic granule docking at the immunologic synapse. Isoform 4 binds phosphatidylserine (PS) and phosphatidylinositol-4,5-bisphosphate (PIP2) and promotes the recruitment of glucagon-containing granules to the cell membrane in pancreatic alpha cells. Binding to PS is inhibited by Ca(2+) while binding to PIP2 is Ca(2+) insensitive.<ref>PMID:18812475</ref> <ref>PMID:17182843</ref> <ref>PMID:18266782</ref> | ||
