Proteasome maturation factor Ump1 (IPR008012)

Short name: Ump1

Overlapping homologous superfamilies


Family relationships



Ump1 is a short-lived chaperone present in the precursor form of the 20S proteasome and absent in the mature complex. Ump1 is required for the correct assembly and enzymatic activation of the proteasome. Ump1 seems to be degraded by the proteasome upon its formation [PMID: 9491890, PMID: 17431397].
