bsm-70496M

DATASHEET

Host: Mouse

Target Protein: Fascin (clone 55K2)

Specificity: The antibody detects a 55 kDa* band corresponding to fascin on SDS-PAGE immunoblots of human A431 and HeLa, as well as mouse C2C12 and rat PC12.

Clonality: Monoclonal

Isotype: IgG1

Swiss Prot: Q16658

Source: Clone (55K2) was generated from full-length human fascin purified from HeLa cells. This sequence has high homology to rat and mouse fascin.

Purification: Purified by Protein A.

Storage Buffer: PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Background:

Fascin is an actin filament bundling protein localized to lamellipodia and filopodia where it has important roles in cell motility. Regulation of fascin occurs through PKC-mediated phosphorylation of Ser-39 in the F-actin binding site. Cell permeant peptides that block PKC phosphorylation of Ser-39 increase cell migration, while peptides that block fascin binding to F-actin alter lamellipodial morphology and cause aberrant cell motility. Studies using RNA interference of fascin show that fibroblasts have reduced number and abnormal morphology of filopodia, while Ser-39 phosphorylation status may determine filopodial frequency. In Drosophila neurons, fascin deficiency causes alterations in actin filaments and leads to abnormal morphology of developing neurons. Thus, fascin is a critical element of actin-based motility in various cell types.
