Revvity Htrf Human Phospho-Vav1 (Tyr174) Detection Kit, 500 Assay Points

Revvity vav1, also known as vav proto-oncogene 1, is a protein that plays a crucial role in cellular signaling and immune responses. it is primarily expressed in cells of hematopoietic origin, including t cells, b cells, and natural killer cells.vav1 acts as a guanine nucleotide exchange factor (gef) for the rho family gtpases, including rac1, rac2, and rhoa. vav1 activates these gtpases by promoting the exchange of gdp (guanosine diphosphate) for gtp (guanosine triphosphate) on these enzymes. through this mechanism, vav1 is an important regulator of essential cellular processes such as cytoskeletal rearrangement, cell adhesion, proliferation, and migration.in immune cells, vav1 is an important intermediary in the downstream signaling of specialized antigen receptors, including t cell receptors (tcrs) and b cell receptors (bcrs). as such, vav1 has been implicated in several diseases, including the autoimmune disorders systemic lupus erythematosus (sle) and rheumatoid arthritis (ra). in these conditions, abnormal vav1 signaling can contribute to immune dysregulation and inflammation. additionally, vav1 is involved in certain types of cancer, where aberrant activation can promote cellular transformation and metastasis. - PEMSD (Additional S&H Or Hazmat Fees May Apply)
