ACVR1B (Activin receptor type-1B) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Pancreatic ductal adenocarcinoma, Colorectal cancer, Breast cancer and 4 more.
Transmembrane serine/threonine kinase activin type-1 receptor forming an activin receptor complex with activin receptor type-2 (ACVR2A or ACVR2B). Transduces the activin signal from the cell surface to the cytoplasm and is thus regulating a many physiological and pathological processes including neuronal differentiation and neuronal survival, hair follicle development and cycling, FSH production by the pituitary gland, wound healing, extracellular matrix production, immunosuppression and carcinogenesis. Activin is also thought to have a paracrine or autocrine role in follicular development in the ovary.
Open Targets scores its association with cancer at 0.77 (direct and indirect evidence; datatypes literature 0.89, genetic association 0.47, somatic mutation 0.90). IntOGen calls it a driver in 8 cohorts (0 activating, 8 loss-of-function), covering Invasive Breast Carcinoma, Colon Adenocarcinoma, Colorectal Adenocarcinoma, Lung Adenocarcinoma, Pancreatic Adenocarcinoma.

No product in this corpus aims at ACVR1B yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.

Transmembrane serine/threonine kinase activin type-1 receptor forming an activin receptor complex with activin receptor type-2 (ACVR2A or ACVR2B). Transduces the activin signal from the cell surface to the cytoplasm and is thus regulating a many physiological and pathological processes including neuronal differentiation and neuronal survival, hair follicle development and cycling, FSH production by the pituitary gland, wound healing, extracellular matrix production, immunosuppression and carcinogenesis. Activin is also thought to have a paracrine or autocrine role in follicular development in the ovary. Within the receptor complex, type-2 receptors (ACVR2A and/or ACVR2B) act as a primary activin receptors whereas the type-1 receptors like ACVR1B act as downstream transducers of activin signals. Activin binds to type-2 receptor at the plasma membrane and activates its serine-threonine kinase. The activated receptor type-2 then phosphorylates and activates the type-1 receptor such as ACVR1B. Location: Cell membrane (UniProt). Locus 12q13.13 (HGNC).
