補足情報

This supplementary information is collated from multiple sources and compiled automatically.

The proteasome LMP2 also known as proteasome subunit beta type-1 or PSMB9 is a component important in the functioning of the 20S proteasome complex. This molecular entity with a mass of approximately 23 kDa is predominantly expressed in immune cells including lymphocytes. LMP2 incorporates into the immunoproteasome a specialized variant of the proteasome that participates prominently in the processing of class I MHC peptides enhancing the immune response.
Biological function summary

LMP2 is integral to protein catabolism and regulation of the cellular protein homeostasis. As part of the larger proteasome complex the LMP2 protein functions in degradative pathways that recycle amino acids from ubiquitin-tagged proteins. This proteasome takes part in antigen processing helping convert proteins into peptides that are presented on the surface of cells for immune system recognition.

Pathways

LMP2 is significantly involved in the ubiquitin-proteasome pathway and immune system processes. It interacts with other immunoproteasome subunits like LMP7 and MECL-1 which work together to enhance the proteolytic capacity for antigen presentation. The presence of LMP2 in these pathways demonstrates its role in adaptive immunity contributing to the clearance of misfolded or damaged proteins and therefore maintaining cell health.

LMP2 associates with immune-related conditions and some cancer types. Dysregulation of LMP2 expression or function can impact antigen presentation potentially leading to autoimmune disorders due to inappropriate immune activation. Moreover alterations in LMP2 expression have been observed in certain cancers such as melanoma where it affects proteasome activity and influences tumor progression. In these contexts interactions with proteins like TAP1 and TAP2 which aid in peptide transport mark its relevance in disease pathogenesis.

ターゲットの情報

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 (PubMed : 33727065, PubMed : 34819510). The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues.
