Protein attributes

Sequence length	567 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Acts as a signal transducer. Phosphorylates TGFBR1 upon binding to its ligand, TGF-beta. TGFBR1 in turn phosphorylates the cytoplasmic effectors of the pathway, known as SMADs. On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for TGF-beta.
Catalytic activity	ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
Cofactor	Magnesium or manganese By similarity.
Subunit structure	Binds to DAXX. Interacts with TCTEX1D4 By similarity.
Subcellular location	Membrane; Single-pass type I membrane protein.
Post-translational modification	Phosphorylated on a Ser/Thr residue in the cytoplasmic domain.
Sequence similarities	Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily. Contains 1 protein kinase domain.
