General annotation (Comments)

Function	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 activin A, activin B and inhibin A. May modulate neuropeptide expression in dorsal root ganglia (DRG) neurons and ovarian follicle development. Ref.1 Ref.2 Ref.3 Ref.5
Catalytic activity	ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
Cofactor	Magnesium or manganese By similarity.
Subcellular location	Membrane; Single-pass type I membrane protein By similarity.
Tissue specificity	Not expressed in hen anterior pituitary during the ovulatory cycle but expressed in the ovarian follicle. Ref.4 Ref.5
Developmental stage	Expressed during the differentiation of neuroepithelium, of myotomes to muscle and of surface extoderm. Expressed in the dorsal root ganglia (DRG). Ref.1 Ref.2 Ref.3
Induction	By activin. Ref.1
Sequence similarities	Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily. Contains 1 protein kinase domain.
