IGFBP3 分子靶点综述

胰岛素样生长因子结合蛋白3(IGFBP-3),在人类中由IGFBP3基因编码。IGFBP-3是六个IGF结合蛋白(IGFBP-1至6)中的一个,这些结合蛋白具有高度保守结构,并可高亲和力结合IGF-1和IGF-2。IGFBP-3是血液中IGF的主要转运蛋白。它与细胞表面蛋白相互作用,影响胞外或内化后的细胞信号,它也可进入细胞核,在这里,它结合核激素受体和其它配体。基于细胞生长实验、动物癌症模型和流行病学研究,IGFBP-3似乎可作为低外显率的肿瘤抑制基因。失调的IGFBP-3参与许多癌症。血清中IGFBP-3水平可用来筛选生长激素是否缺乏。在AIDS、不受控制的糖尿病、创伤和严重烧伤患者的血清中,IGFBP-3水平是下降的。

人 Human IGFBP3靶点分子功能(预测)

Enables insulin-like growth factor I binding activity and protein tyrosine phosphatase activator activity. Involved in several processes, including negative regulation of smooth muscle cell migration; negative regulation of smooth muscle cell proliferation; and positive regulation of myoblast differentiation. Acts upstream of or within negative regulation of cell population proliferation; negative regulation of protein phosphorylation; and protein phosphorylation. Located in extracellular space and nucleus. Part of insulin-like growth factor ternary complex. Implicated in several diseases, including Alzheimer's disease; Turner syndrome; diabetes mellitus (multiple); prostate cancer; and transitional cell carcinoma. Biomarker of several diseases, including Barrett's esophagus; Down syndrome; autoimmune disease (multiple); bone disease (multiple); and urinary system cancer (multiple).
