TGF beta Receptor I (TGFBR1) Human Recombinant Protein

Specifications

Product Data
Species	Human
Protein Source	Human
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) Leu34-Glu125
Tag	C-Fc
Buffer	Lyophilized from a 0.2 um filtered solution of PBS, pH7.4.
Note	Recombinant Human TGF-beta Receptor Type-1 is produced by our Mammalian expression system and the target gene encoding Leu34-Glu125 is expressed with a Fc tag at the C-terminus.

Summary	TGF-beta RI, also called ALK-5, is an approximately 55 kDa type I transmembrane serine/threonine receptor kinase. In the presence of TGF-beta, TGF-beta RI forms a complex with, and is phosphorylated by, TGF-beta RII. Phosphorylated TGF-beta RI can then transiently bind and phosphorylate Smad2 and Smad3. TGF-beta functions as a tumor suppressor by inhibiting the cell cycle in the G1 phase. Administration of TGF-beta is able to protect against mammary tumor development in transgenic mouse models in vivo. Disruption of the TGF-beta/SMAD pathway has been implicated in a variety of human cancers, with the majority of colon and gastric cancers being caused by an inactivating mutation of TGF-beta RII. TGF-beta RI is likely important during development, since mice deficient for TGF-beta RI die at midgestation with severe defects in vascular development of the yolk sac and placenta, and an absence of circulating red blood cells. Furthermore, TGF-beta RI appears to be involved in proper lymphatic network development.
