Summaries for PSMB8 Gene

Entrez Gene Summary for PSMB8 Gene

  • The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a member of the proteasome B-type family, also known as the T1B family, that is a 20S core beta subunit. This gene is located in the class II region of the MHC (major histocompatibility complex). Expression of this gene is induced by gamma interferon and this gene product replaces catalytic subunit 3 (proteasome beta 5 subunit) in the immunoproteasome. Proteolytic processing is required to generate a mature subunit. Two alternative transcripts encoding two isoforms have been identified; both isoforms are processed to yield the same mature subunit.

GeneCards Summary for PSMB8 Gene

PSMB8 (Proteasome (Prosome, Macropain) Subunit, Beta Type, 8) is a Protein Coding gene. Diseases associated with PSMB8 include autoinflammation, lipodystrophy, and dermatosis syndrome and jmp syndrome. Among its related pathways are Signaling by GPCR and Downstream Signaling Events Of B Cell Receptor (BCR). GO annotations related to this gene include threonine-type endopeptidase activity. An important paralog of this gene is PSMB11.

UniProtKB/Swiss-Prot for PSMB8 Gene

  • 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. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB5 by PSMB8 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues. Acts as a major component of interferon gamma-induced sensitivity. Plays a key role in apoptosis via the degradation of the apoptotic inhibitor MCL1. May be involved in the inflammatory response pathway. In cancer cells, substitution of isoform 1 (E2) by isoform 2 (E1) results in immunoproteasome deficiency. Required for the differentiation of preadipocytes into adipocytes.

    Quaternary structure:
    • 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. Component of the immunoproteasome, where it displaces the equivalent housekeeping subunit PSMB5. Component of the spermatoproteasome, a form of the proteasome specifically found in testis. Directly interacts with POMP. Interacts with HIV-1 TAT protein. Interacts with TAP1.

Accompanying features may include muscle weakness and atrophy, hepatosplenomegaly, and microcytic anemia. {ECO:0000269 PubMed:21129723, ECO:0000269 PubMed:21852578, ECO:0000269 PubMed:21881205}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Mutation Met-75 has been found in chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome (CANDLE syndrome). CANDLE patients have some overlapping features with NKJO patients, including a cutaneous eruption and lipodystrophy. They show a characteristic neutrophilic dermatosis with a mononuclear interstitial infiltrate in the dermis that seems pathognomonic for CANDLE syndrome (PubMed:21953331). {ECO:0000269 PubMed:21953331}.
