Description
The protein encoded by this gene forms a heteromeric complex with type II TGF-beta receptors when bound to TGF-beta, transducing the TGF-beta signal from the cell surface to the cytoplasm. The encoded protein is a serine/threonine protein kinase. Mutations in this gene have been associated with Loeys-Dietz aortic aneurysm syndrome (LDAS). Multiple transcript variants encoding different isoforms have been found for this gene.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human TGF-beta RII Fc Chimera is immobilized at 1 μg/mL (100 μL/well), it binds Recombinant Human (rh) TGF-beta RI/ALK-5 Fc Chimera in the presence of rhTGF-beta 1. The concentration of rhTGF-beta RI Fc Chimera that produces 50% of the optimal binding response is approximately 0.05-0.4 μg/mL.
