Official Full Name proteasome (prosome, macropain) subunit, alpha type, 3
Background The 20S proteasome is the major proteolytic enzyme complex involved in intracellular protein degradation. It consists of four stacked rings, each with 7 distinct subunits. The two outer layers are identical rings composed of alpha subunits (called PSMAs),
Synonyms PSMA3; proteasome (prosome, macropain) subunit, alpha type, 3; proteasome subunit alpha type-3; HC8; macropain subunit C8; proteasome subunit C8; proteasome component C8; multicatalytic endopeptidase complex subunit C8; PSC3; MGC12306; MGC32631
