Proteasome subunit beta type-9 as known as 20S proteasome subunit beta-1i is a protein that in humans is encoded by the PSMB9 gene.

This protein is one of 17 major units, which contributes to the complete Assembly of the proteasomal complex 20C. In particular, proteasome subunit beta Type-5, along with other beta-subunits that assemble into two heptameric rings and subsequently the proteolytic chamber for the decomposition of raw materials. This protein contains a "trypsin-like" and is able to crack after basic residues of the peptide. In the eukaryotic proteasome have recognized the decomposition of proteins, including damaged proteins protein for quality control purposes or the key regulatory protein components for dynamic biological processes. Constitutive subunits beta1, beta2, and beta 5 systematic nomenclature can be replaced by their inducible analogues beta1i, 2I, 5I and when the cells in the treatment of interferon-γ. The result of proteasomal complex is the so-called immunoproteasome. An important function of a modified proteasomal complex, immunoproteasome, is the processing of numerous class-I MHC restricted T-cell epitopes.
