RAP1GAP2

RAP1 GTPase activating protein 2 is a is_associated_with::protein in humans that is encoded by the RAP1GAP2 is_associated_with::gene.

This gene encodes a is_associated_with::GTPase-activating protein that activates the small guanine-nucleotide-binding protein is_associated_with::Rap1 in is_associated_with::platelets. The protein interacts with synaptotagmin-like protein 1 and Rab27 and regulates is_associated_with::secretion of is_associated_with::dense granules from platelets at sites of is_associated_with::endothelial damage. Multiple transcript variants encoding different is_associated_with::isoforms have been found for this gene. [provided by RefSeq, Sep 2009].
