FSCN1, Recombinant, Human (Fascin, 55kD Actin-bundling Protein, Singed-like Protein, p55, FAN1, HSN,

FSCN1 is an actin-bundling protein that provides rigidity to filopodial bundles to efficiently push the membrane forward during cytoskeleton remodeling and cell migration. Probably involved in the assembly of actin filament bundles present in microspikes, membrane ruffles, and stress fibers. And this protein is absent from most normal epithelia yet is upregulated in multiple forms of human carcinoma, where its expression correlates clinically with a poor prognosis. FSCN1 expression has been localized to neurons, glial cells, and endothelial cells. Source: Recombinant corresponding to aa1-493 of human FSCN1 protein, fused to His-tag at N-terminus, expressed in E.coli.
