产品描述 概述Insulin-like Growth Factor-Binding Protein 7 (IGF-BP7) belongs to the IGFBP family, which are all cysteinerich proteins with conserved cysteine and have an IGFBP domain, a Kazal-like domain and an Ig-like C2-type domain. IGF-BP7 is expressed in a wide range of normal human tissues and it generally shows reduced expression in cancer cell lines of prostate, breast, colon, and lung origin. It plays a role in skeletal myogenesis by binding to IGF in a manner that inhibits IGF induced differentiation of skeletal myoblasts, without affecting IGF induced proliferation. Additionally, IGF-BP7 suppresses growth and colony formation of prostate and breast cancer cell lines through an IGF independent mechanism, which causes a delay in the G1 phase of the cell cycle, and increased apoptosis. Mature human IGF-BP7 contains 256 a.a. with one potential N-linked glycosylation site. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes.
