General description

Metavinculin (MV) and its a.a. 916-983 truncated splice variant Vinculin (UniProt P18206) are cytoskeleton proteins encoded by the VCL (also known as MVCL, CMD1W, CMH15) gene (Gene ID 7414) in human. The N-terminal globular head domain (a.a. 2-835) of Vinculin/VM contains binding sites for talin and α-actinin as well as a tyrosine phosphorylation site, while their C-terminal Tail region (a.a. 879-1134 of VM; a.a. 879-1066 of Vinculin) contains binding sites for F-actin, paxillin, and lipids. Vinculin is associated with focal adhesion and adherens junctions, which are complexes that nucleate actin filaments and crosslinkers between the external medium, plasma membrane, and actin cytoskeleton. The loss of vinculin disrupts focal adhesion complex formation and prevents cell adhesion and spreading, accompanied by reduced stress fiber formation and inhibition of lamellipodia extension. Smooth muscles and skeletal muscles in their well-differentiated, contractile state co-express vinculin and meta-vinculin. Both vinculin isoforms co-localize in muscular adhesive structures, such as dense plaques in smooth muscles, intercalated discs in cardiomyocytes, and costameres in skeletal muscles.

Quality

Evaluated by Western Blotting in HepG2 cell lysate.

Western Blotting Analysis: 0.5 µg/mL of this antibody detected Viculin in 10 µg of HepG2 cell lysate.

Specificity

Clone VII F9 (7F9) reacted equally with human vinculin and meta-vinculin by immunoblotting and recognized all vinculin (α, α′, β, γ) and meta-vinculin (α & β) variants resolved by isoelectrofocusing (Glukhova, M.A., et al. (1990). J. Biol. Chem. 265:13042-13046).

Storage and Stability

Stable for 1 year at 2-8°C from date of receipt.

Target description

~130 kDa observed. Target band size appears larger than the calculated molecular weights of 116.7 kDa (Vinculin; isoform 1) and 123.80 kDa (Metainculin; isoform 2).
