IL6ST / gp130蛋白背景综述
Glycoprotein 130 (gp130), also known as IL6ST, IL6R-beta and CD130, is a common signal-transducing molecule shared by the functional receptor complexes of the IL-6 family of cytokines (IL-6, IL-11, leukemia inhibitory factor (LIF), granulocyte colonystimulating factor, ciliary neurotrophic factor, and cardiotrophin-1). It belongs to the class a…? cytokine receptor family, and was found in tissues such as brain, heart, thymus, spleen, kidney, lung and liver. Mouse gp130 contains five fibronectin type-III domains, and one Ig-like C2-type (immunoglobulin-like) domain. gp130 is an important part of many different types of signaling complexes. It binds to IL6/IL6R (alpha chain) complex, resulting in the formation of high-affinity IL6 binding sites, and transduces the signal. This complex of 3 proteins then homodimerizes to form a hexameric complex which can produce downstream signals. Inactivation of gp130 is lethal to mice. The mice homozygous for a knock-in mutation in gp130 ( Y757F/Y757F ) that leads to gp130-dependent signal transducers and activators of transcription (STAT) 1/3 hyperactivation develop a broad spectrum of hematopoietic abnormalities, including splenomegaly, lymphadenopathy, and thrombocytosis. gp130 is also involved in various human diseases, such as liver disease, coronary artery disease and myocardial infarction. Furthermore, gp130 is widely expressed in breast cancer cell lines and primary tumors, thus it have been implicated in constitutive STAT3 activation in breast cancer.
