Supplementary information

Proteasome 20S LMP7 also known as β5i or PSMB8 is a subunit of the immunoproteasome. It weighs about 23 kDa and it is expressed predominantly in immune cells such as lymphocytes and macrophages. LMP7 is part of the proteasome 20S a cylindrical core particle involved in the degradation of ubiquitinated proteins. This process helps maintain protein homeostasis by breaking down misfolded and damaged proteins.
Biological function summary

The immunoproteasome in which LMP7 is an essential component plays an important role in the adaptive immune system. It influences the generation of antigenic peptides that are presented on MHC class I molecules. LMP7's expression is increased during immune responses particularly following gamma interferon (IFN-γ) stimulation contributing to the immune-mediated proteasome conformation. The immunoproteasome enables more efficient peptide processing enhancing antigen presentation to cytotoxic T lymphocytes.

Pathways

LMP7 is involved in the MHC class I antigen presentation pathway. This pathway allows the immune system to detect and respond to intracellular pathogens such as viruses. Additionally LMP7 interacts with TAP (Transporter associated with Antigen Processing) and other proteasome subunits to ensure effective peptide processing for loading onto MHC class I molecules. Through this involvement it closely links to immune signaling and cellular stress responses.

Research shows that LMP7 connects to autoimmune diseases and inflammatory disorders such as lupus and rheumatoid arthritis. Dysregulation of LMP7 expression or activity can lead to improper immune responses contributing to disease pathogenesis. Furthermore LMP7 impacts the degradation of specific proteins relevant to these conditions. For example it works alongside other proteasome subunits like LMP2 and MECL-1 in modulating the inflammatory response which can exacerbate autoimmune disease symptoms.

Target data

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. Involved in the generation of spliced peptides resulting from the ligation of two separate proteasomal cleavage products that are not contiguous in the parental protein (PubMed : 27049119). 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.
