背景信息

The VAV3 antibody is a research tool used to study the VAV3 protein, a member of the VAV family of guanine nucleotide exchange factors (GEFs). VAV3 plays a critical role in intracellular signaling by activating Rho/Rac GTPases, which regulate processes like cytoskeletal reorganization, cell migration, proliferation, and apoptosis. It contains multiple functional domains, including a calponin homology (CH) domain, an acidic (Ac) region, a Dbl-homology (DH) domain responsible for GEF activity, and pleckstrin homology (PH) and Src homology 2/3 (SH2/SH3) domains that mediate protein interactions. Dysregulation of VAV3 has been implicated in cancer progression, particularly in hormone-sensitive malignancies such as prostate and breast cancer. For example, elevated VAV3 expression is associated with androgen receptor signaling in prostate cancer and may contribute to therapy resistance. Additionally, VAV3 interacts with receptor tyrosine kinases (RTKs) and cytokine receptors, influencing pathways like PI3K/Akt and MAPK. The VAV3 antibody is essential for detecting protein expression, localization, and activity in techniques like Western blotting, immunohistochemistry (IHC), and immunoprecipitation (IP). Its study provides insights into oncogenic mechanisms and potential therapeutic targets.
