ARHGEF7 Antibody – Rabbit Polyclonal

This gene encodes a protein that belongs to a family of cytoplasmic proteins that activate the Ras-like family of Rho proteins by exchanging bound GDP for GTP. It forms a complex with the small GTP binding protein Rac1 and recruits Rac1 to membrane ruffles and to focal adhesions. Multiple alternatively spliced transcript variants encoding different isoforms have been observed for this gene. [provided by RefSeq, Mar 2016]

ARHGEF7: a RAC1 guanine nucleotide exchange factor (GEF). Can induce membrane ruffling. Interacts with PAK kinases through its SH3 domain. Acts both as an activator and a downstream target for Cdc42. Its EGF-dependent phosphorylation activates its nucleotide exchange factor for Cdc42 and regulates its interaction with the E3 ligase Cbl, thus modulating Cbl-catalysed EGFR degradation. Its phosphorylation status is necessary to maintain the balance between normal signaling by EGFR and Src versus aberrant growth and transformation. Four alternatively spliced isoforms have been described.
