CC -!- FUNCTION: Transmembrane serine/threonine kinase activin type-2 receptor
CC forming an activin receptor complex with activin type-1
CC serine/threonine kinase receptors (ACVR1, ACVR1B or ACVR1c). Transduces
CC the activin signal from the cell surface to the cytoplasm and is thus
CC regulating many physiological and pathological processes including
CC neuronal differentiation and neuronal survival, hair follicle
CC development and cycling, FSH production by the pituitary gland, wound
CC healing, extracellular matrix production, immunosuppression and
CC carcinogenesis. Activin is also thought to have a paracrine or
CC autocrine role in follicular development in the ovary. Within the
CC receptor complex, the type-2 receptors act as a primary activin
CC receptors (binds activin-A/INHBA, activin-B/INHBB as well as inhibin-
CC A/INHA-INHBA). The type-1 receptors like ACVR1B act as downstream
CC transducers of activin signals. Activin binds to type-2 receptor at the
CC plasma membrane and activates its serine-threonine kinase. The
CC activated receptor type-2 then phosphorylates and activates the type-1
CC receptor. Once activated, the type-1 receptor binds and phosphorylates
CC the SMAD proteins SMAD2 and SMAD3, on serine residues of the C-terminal
CC tail. Soon after their association with the activin receptor and
CC subsequent phosphorylation, SMAD2 and SMAD3 are released into the
CC cytoplasm where they interact with the common partner SMAD4. This SMAD
CC complex translocates into the nucleus where it mediates activin-induced
CC transcription. Inhibitory SMAD7, which is recruited to ACVR1B through
CC FKBP1A, can prevent the association of SMAD2 and SMAD3 with the activin
CC receptor complex, thereby blocking the activin signal. Activin signal
CC transduction is also antagonized by the binding to the receptor of
CC inhibin-B via the IGSF1 inhibin coreceptor (By similarity).
