  • Function
    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.
  • Tissue specificity
    Detected in platelets, neutrophils and T lymphocytes (at protein level). Expressed in brain where it is enriched in the striatum. Also expressed in the hematopoietic system. Detected in heart, brain, lung, placenta, liver, skeletal muscle and kidney.
  • Sequence similarities
    Belongs to the RASGRP family.
    Contains 2 EF-hand domains.
    Contains 1 N-terminal Ras-GEF domain.
    Contains 1 phorbol-ester/DAG-type zinc finger.
    Contains 1 Ras-GEF domain.
  • Developmental stage
    Expressed in fetal brain, lung, liver and kidney.
  • Domain
    The N-terminal Ras-GEF domain mediates association with F-actin.
  • Post-translational
    Isoform 2 is palmitoylated and myristoylated while isoform 1.
  • Cellular localization
    Cytoplasm > cytosol. Cell membrane. Cell junction > synapse > synaptosome. Cell projection > ruffle membrane. 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.
