Rabbit Anti-Vinexin antibody
Vinexin is a 671 amino acid protein that is expressed as two isoforms, designated Vinexin alpha and Vinexin beta. Localized to cell junctions in both the cytoplasm and the cytoskeleton, Vinexin alpha functions to promote Actin stress fiber formation, playing an important role in modification of the Actin cytoskeleton. Like Vinexin alpha, Vinexin beta is localized to cell junctions in the cytoplasm, but is also found in the nucleus where it plays an important role in cell spreading and in activation of the JNK pathway in response to EGF stimulation. Although Vinexin alpha and Vinexin beta have different roles within the cell, both proteins contain three SH3 domains in their carboxy terminus and are expressed in a variety of tissues, including placenta, heart, liver, brain, pancreas and skeletal muscle. Together, Vinexin alpha and Vinexin beta are involved in cell-cell adhesion, signal transduction and cytoskeletal organization throughout the cell.
Function:
Vinexin is a focal adhesion protein with a sorbin homology (SoHo) domain as well as 3 SH3 domains. It exists as at least three splice variants - alpha, beta and gamma. It is thought to play a key role in cell adhesion, cell spreading and migration and cytoskeletal organisation. It has also been implicated signaling due to its interaction with the extracellular signal-regulated kinase ERK. Binds to vinculin at sites of cell-cell contact.
Subcellular Location:
Localized at cell-extracellular matrix junctions. Both isoforms were localized at focal adhesion and cell-cell adhesion sites, vinexin beta was also found in the nucleus.
