Background
The activin type 2 receptors belong to a larger TGF-beta receptor family and modulate signals for transforming growth factor beta ligands. These receptors are involved in a host of physiological processes including, growth, cell differentiation, homeostasis, osteogenesis, apoptosis and many other functions. There are two activin type two receptors: ACVR2A and ACVR2B. Activin plays a significant role in reproduction. ACVR2 receptors are present in the testis during testicular development. ACR2A and ACVR2B was found to be localized primarily in the gonocytes as well as in sertoli cells.
The ACVR2 gene is often found inactivated in prostate cancer and tumors with microsatellite instability.
