[Term] id: PR:000000006 name: TGF-beta superfamily receptor type-1 def: "A protein that is a translation product of an evolutionary-related gene with core domain composition consisting of an extracellular Activin types I and II receptor domain (Pfam:PF01064), a transmembrane domain, a Transforming growth factor beta type I GS-motif (Pfam:PF08515) and a Protein kinase domain (Pfam:PF00069). The transforming growth factor-beta (TGF-beta) superfamily of receptors comprises two groups of transmembrane serine-threonine kinase receptors, so called type-1, and type-2 receptors, that are activated following engagement by members of the TGF-beta superfamily of ligands. These events specify diverse downstream responses that are differentially regulated by controlling access and activation of the ligands, their receptors and downstream substrates in different cell types. The type 1 receptors are characterized by the presence of a glycine-serine rich juxta-membrane domain (the GS-motif) that is critical for their activation."
