Purity: > 95% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH7.4) containing 10% glycerol. ACTN1 also known as alpha-actinin-1 isoform a. ACTN1 functions as an actin-binding-protein. ACTN1 determines the motility of keratinocytes by regulating the organization of the actin cytoskeleton, focal adhesion, and hemidesmosome proteins complexes, thereby modulating cell speed, lamellipodial dynamics, and directed migration. Recombinant human ACTN1, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
