An Activin receptor is a receptor which binds activin. These proteins are receptor-type kinases of Ser/Thr type, which have a single transmembrane domain and a specific hydrophilic Cys-rich ligand-binding domain.^[1][2][3]

Types include:

• Activin type 1 receptors
• Activin type 2 receptors

Human proteins containing this domain

ACVR1; ACVR1B; ACVR1C; ACVR2A; ACVR2B; ACVRL1; BMPR1A; BMPR1B; BMPR2; TGFBR1;
