Rap guanine nucleotide exchange factor 2 is a protein that in humans is encoded by the RAPGEF2 gene.^[5]^[6]^[7]

RAPGEF2 is a cyclic AMP binding protein.^[8]^[9]

Function

Members of the RAS subfamily of GTPases function in signal transduction as GTP/GDP-regulated switches that cycle between inactive GDP- and active GTP-bound states. Guanine nucleotide exchange factors (GEFs) such as RAPGEF2 serve as RAS activators by promoting acquisition of GTP to maintain the active GTP-bound state and are the key link between cell surface receptors and RAS activation.^[6]

Interactions

RAPGEF2 has been shown to interact with RAP1A^[6] and RALGDS.^[10]
