ACVRL1 cDNA Clone – Activin A Receptor Type II-Like 1 (Human)

This gene encodes a type I cell-surface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The encoded protein, sometimes termed ALK1, shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. Mutations in this gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2. [provided by RefSeq, Jul 2008]

ALK1: a kinase of the STKR family. A type I cell-surface receptor for the TGF-beta superfamily of ligands including Activin A. Highly expressed in human placenta and lung. Deficiency causes hemorrhagic telangiectasia type 2 also known as Rendu-Osler-Weber syndrome 2.
