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. Note: This description may include information from UniProtKB.
