IGFBP7 His Recombinant Protein

Source : Escherichia Coli. IGFBP7 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 279 amino acids (27-282 a.a.) and having a molecular mass of 28.8kDa.IGFBP7 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Insulin-like Growth Factor-Binding Protein 7 (IGFBP7) is a member of the IGFBP family. IGFBP family members are all cysteine rich proteins with conserved cysteine and have an IGFBP domain, a Kazal-like domain and an Ig-like C2-type domain. IGFBP7 is expressed in a broad range of normal human tissues and it mostly shows reduced expression in cancer cell lines of prostate, breast, colon, and lung origin. IGFBP7 has a role in skeletal myogenesis by binding to IGF in a manner which inhibits IGF induced differentiation of skeletal myoblasts, without disturbing IGF induced proliferation. Moreover, IGFBP7 suppresses growth and colony formation of prostate and breast cancer cell lines via an IGF independent mechanism, which triggers a delay in the G1 phase of the cell cycle, and increased apoptosis.
