Function

[GRP2_HUMAN] Functions as a calcium- and DAG-regulated nucleotide exchange factor specifically activating Rap through the exchange of bound GDP for GTP. May also activates other GTPases such as RRAS, RRAS2, NRAS, KRAS but not HRAS. Functions in aggregation of platelets and adhesion of T-lymphocytes and neutrophils probably through inside-out integrin activation. May function in the muscarinic acetylcholine receptor M1/CHRM1 signaling pathway.[1] [2] [3] [4]

About this Structure

2ma2 is a 1 chain structure with sequence from Homo sapiens. Full experimental information is available from OCA.
