Background
VAV1 is a crucial signaling protein that belongs to the VAV family of guanine nucleotide exchange factors (GEFs). It plays a pivotal role in hematopoietic cells, where it regulates cytoskeletal dynamics, cell migration, and immune responses by activating Rho-family GTPases such as Rac1 and Cdc42. The protein contains multiple functional domains, including a Dbl homology (DH) domain for GEF activity, a pleckstrin homology (PH) domain, and two Src homology 3 (SH3) domains, with the second SH3 domain (SH3-2) mediating protein-protein interactions. VAV1 is primarily expressed in T cells, B cells, and natural killer (NK) cells, where it participates in T-cell receptor (TCR) and B-cell receptor (BCR) signaling pathways. Dysregulation of VAV1 has been linked to autoimmune diseases and hematological malignancies.
