Function

Activin receptors (Acvr) are integral to the activin and myostatin signalling pathway. Binding of activin to the Acvr on muscle cell membrane leads to enhanced muscle protein breakdown and debilitating loss of muscle mass and functional capacity^[1].

Acvr1 is involved in bone, heart, cartilage, nervous and reproductive system development and regulation^[2].

Disease

A mutation in Acvr1 exists in individuals with the rare developmental disorder fibrodysplasia ossificans progressiva^[3].

Relevance

Increased activin/Acvr2 signalling links aging and heart failure pathobiology and that targeted inhibition of this catabolic pathway may form a therapeutic strategy for multiple forms of hear failure^[4].

Structural highlights

3D structure of the kinase domain of Acvr1 complex with inhibitor shows the inhibitor forming various interactions with the protein including a hydrogen bonds to His residues and a water bridged hydrogen bond to the catalytic lysine^[5]. Water molecule is shown as red sphere.
