Western blot - Human VAV2 knockout HeLa cell lysate (AB257794)

Lane 1 : Wild-type HeLa cell lysate (20µg)

Lane 2 : VAV2 knockout HeLa cell lysate (20µg)

Lanes 1- 2 : Merged signal (red and green). Green - ab52640 observed at 100 kDa. Red - loading control ab8245 observed at 37 kDa.

ab52640 Anti-VAV2 antibody [EP1067Y] was shown to specifically react with VAV2 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265318 (knockout cell lysate ab257794) was used. Wild-type and VAV2 knockout samples were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab52640 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 20000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

VAV2 also known as Vav 2 guanine nucleotide exchange factor is a member of the VAV family of proteins which function as guanine nucleotide exchange factors (GEFs). It has a molecular mass of approximately 100 kDa. The protein converts inactive GDP-bound Rho family GTPases such as Rac1 and Cdc42 into their active GTP-bound form. VAV2 is expressed in various tissues including the brain heart and lung indicating its broad role in cellular signaling across different systems.
Biological function summary

VAV2 influences multiple cellular processes through its role as a GEF. This protein does not form a part of a static complex but interacts dynamically with other signaling components. VAV2 regulates cytoskeleton organization cell migration and growth by activating Rho family GTPases. Its activity impacts processes such as neuronal development and immune response by modifying the actin cytoskeleton which is important for cell movement and morphological changes.

Pathways

VAV2 plays an integral role in signaling cascades like the Ras and MAPK pathways. It interacts closely with proteins like Rac1 and Cdc42 to propagate signals that influence cell proliferation and survival. By facilitating the switch from inactive GDP-bound states to active GTP-bound forms of Rho GTPases VAV2 integrates signals from cell surface receptors to downstream effectors that mediate cellular responses to external stimuli.

VAV2’s function connects to cancer progression and cardiovascular disorders. Changes in VAV2 expression or activity can lead to abnormal cell growth and differentiation linking it to cancerous transformations. Additionally because VAV2 modulates cell migration and cytoskeletal dynamics its malfunction can contribute to cardiovascular diseases by affecting vascular smooth muscle cells and endothelial cells. In both contexts VAV2's interactions with Rho family proteins like Rac1 highlights its influence in disease mechanisms.
