Activity summary

PSMB10 also known as MECL1 is a proteasome component involved in protein degradation. This protein has a molecular mass of approximately 29 kDa. PSMB10 is expressed in various tissues with notable expression in the immune system. As a beta subunit of the 20S proteasome MECL1 has a role in cleaving peptides at specific sites contributing to the breakdown of ubiquitinated proteins.

Biological function summary

PSMB10/MECL1 plays a significant role in immune responses. It forms part of the immunoproteasome a variant of the proteasome complex which enhances the generation of antigenic peptides presented on MHC class I molecules. This function is essential for effective immune surveillance and initializing adaptive immunity. In particular PSMB10's influence on antigen processing positions it as an important player in modulating immune system activity.

Pathways

PSMB10/MECL1 participates in pathways associated with protein catabolism and immune signaling. It is involved in the ubiquitin-proteasome pathway which is critical for maintaining cellular protein balance. The function of PSMB10 within the immunoproteasome links it to immune signaling pathways. It has associations with other 20S proteasome subunits such as PSMB8 and PSMB9 which also contribute to the formation of the immunoproteasome complex.

Associated diseases and disorders

PSMB10/MECL1 has connections to autoimmune diseases and cancer. In autoimmune diseases the altered function of PSMB10 within the immunoproteasome can lead to improper antigen presentation potentially triggering excessive immune responses. In oncology aberrant expression of immunoproteasome subunits including PSMB10 has implications in tumor immune evasion. The interplay with proteins like PSMB9 in these contexts suggests an intricate network affecting disease progression and immune regulation.
