This gene encodes a RAC1-specific guanine nucleotide exchange factor (GEF), which promotes the exchange of GDP for GTP on RAC1, activating it to bind downstream effectors. This activation regulates RAC1 signaling pathways involved in cell shape, migration, adhesion, growth, survival, polarity, cytoskeletal dynamics, endocytosis, and membrane trafficking, playing key roles in invasion, metastasis, and cancer. The encoded protein also activates other Rho-like GTPases including CDC42, RAC2, RAC3, and RHOA. Multiple isoforms exist, differing in domain composition. All have C-terminal Dbl homology (DH) and pleckstrin homology (PH) domains, while only longer isoforms have an N-terminal myristoylation site, additional PH and ras-binding domains, and a PDZ domain. These isoforms interact with various proteins and lipids, undergoing complex regulation.
