Identification
HMDB Protein ID HMDBP11493
Secondary Accession Numbers
  • 17844
Name Rho guanine nucleotide exchange factor 4
Synonyms
  1. APC-stimulated guanine nucleotide exchange factor
  2. Asef
Gene Name ARHGEF4
Protein Type Unknown
Biological Properties
General Function Involved in Rho guanyl-nucleotide exchange factor activity
Specific Function Acts as guanine nucleotide exchange factor (GEF) for RhoA and RAC1 GTPases. Binding of APC may activate RAC1 GEF activity. The APC-ARHGEF4 complex seems to be involved in cell migration as well as in E-cadherin-mediated cell-cell adhesion
