Anti-GRP2

Protein function: Functions as a calcium- and DAG-regulated nucleotide exchange factor specifically activating Rap through the exchange of bound GDP for GTP. May also activate 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. [The UniProt Consortium] Recommended dilutions: WB 1:1000-2000. Cellular localization: Cytoplasm, cytosol. Cell membrane, Peripheral membrane protein. Cell junction, synapse, synaptosome . Cell projection, ruffle membrane , Peripheral membrane protein . Found both in the cytosol and associated with membranes. Isoform 2 mainly localizes to the cell membrane. Enriched at juxtamembrane areas and membrane ruffles through association with F-actin. Localizes to the cell bodies and axons of striatal neurons (By similarity). .
