Recombinant Human WISP1 Protein (C-His Tag)

WNT1-inducible-signaling pathway protein 1 (WISP-1), also known as CCN4, is a matricellular protein that in humans is encoded by the WISP1 gene. WISP-1 is highly homologous to CYR61 (CCN1) and CTGF (CCN2), and is a member of the CCN family of secreted, extracellular matrix (ECM) -associated signaling proteins (CCN intercellular signaling protein) . The CCN family of proteins shares a common molecular protein structure, characterized by an N-terminal secretory signal peptide followed by four distinct domains with homologies to insulin-like growth factor binding protein (IGFBP), von Willebrand type C repeats (vWC), thrombospondin type 1 repeat (TSR), and a cysteine knot motif within the C-terminal (CT) domain. This family of proteins regulates diverse cellular functions, including cell adhesion, migration, proliferation, differentiation, and survival.
