Protein

Proteasome subunit alpha type-7

Gene
Psma7
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. Inhibits the transactivation function of HIF-1A under both normoxic and hypoxia-mimicking conditions By similarity. The interaction with EMAP2 increases the proteasome-mediated HIF-1A degradation under the hypoxic conditions By similarity. Promotes MAVS degradation and thereby negatively regulates MAVS-mediated innate immune response By similarity.1 Publication

Catalytic activityi

Cleavage of peptide bonds with very broad specificity.

Interactioni

Subunit structurei

PSMA7 interacts directly with the PSMG1-PSMG2 heterodimer which promotes 20S proteasome assembly. Interacts with HIF1A By similarity. Interacts with RAB7A By similarity. Interacts with PARK2 By similarity. Interacts with EMAP2 By similarity. Interacts with MAVS By similarity. The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel.2 Publications
