CTGFL/WISP-2 is a 28.6kD protein that belongs to the CCN family of cysteine rich regulatory proteins.Members of this family stimulate mitosis, adhesion, apoptosis, extracellular matrix production, growth arrest, and migration of multiple cell types.The protein is expressed in primary osteoblasts, fibroblasts, ovary, testes, and heart.In addition to promoting adhesion of osteoblasts, CTGFL/WISP-2 inhibits osteocalcin production, as well as binding of fibrinogen to integrin receptors. Recombinant human CTGFL/WISP-2 is a 24.3kD protein of 228 amino acid residues.
