Target type: cellularcomponent
A multisubunit barrel shaped endoprotease complex, which is the core of the proteasome complex. [GOC:rb, PMID:10806206]
The proteasome core complex is a cylindrical structure composed of four stacked rings, forming a central channel. The two outer rings are composed of seven alpha subunits, while the two inner rings are composed of seven beta subunits. The alpha subunits form the outer surface of the complex and are involved in recognizing and binding substrate proteins. The beta subunits form the inner surface of the complex and are responsible for proteolytic activity. The beta subunits contain active sites that cleave peptide bonds within substrate proteins. The proteasome core complex is responsible for degrading misfolded, damaged, or unwanted proteins in the cell. This process is crucial for maintaining cellular homeostasis and preventing the accumulation of toxic protein aggregates.'
