補足情報

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

Proteasome subunit beta type 2 also known as PSMB2 is a part of the proteasome complex which plays an important role in protein degradation. PSMB2 has a mass of about 22 kDa and functions within the multi-catalytic proteinase complex known as the 20S proteasome core particle. This protein is expressed in various tissues with significant activities found in cells that demand high protein turnover. PSMB2 contributes to the proteasome's chymotrypsin-like activity aiding in the breakdown of damaged or unneeded proteins into peptides.

Biological function summary

Proteasome subunit beta type 2 is essential in maintaining protein homeostasis. It functions as a component of the 20S core of the 26S proteasome where it participates in degrading ubiquitin-tagged proteins. This complex also regulates multiple cellular processes including cell cycle progression and signal transduction. Proper function of PSMB2 is necessary for removing misfolded or damaged proteins thereby preventing their accumulation which could be toxic to cells.

Pathways

Proteasome subunit beta type 2 has a role in the ubiquitin-proteasome pathway which is important for protein degradation and turnover. This pathway contributes to important cellular processes such as DNA repair and antigen processing. PSMB2 in this context is linked to other proteins like ubiquitin-ligase that mediate the tagging of proteins for degradation. Another pathway involving PSMB2 is the NF-kB signaling pathway which controls inflammatory responses and immune system regulation.

Proteasome subunit beta type 2 has been implicated in neurodegenerative diseases like Parkinson’s. The dysregulation or malfunctioning of the proteasome complex might result in protein aggregation seen in such disorders. Additionally PSMB2 is associated with certain cancers due to its role in regulating apoptosis and cellular proliferative activities. Proteins like p53 which is important for tumor suppression are related to PSMB2 through these disease mechanisms highlighting its significance in maintaining normal cellular function and preventing disease progression.

ターゲットの情報

Non-catalytic component of the 20S core proteasome complex involved in the proteolytic degradation of most intracellular proteins. This complex plays numerous essential roles within the cell by associating with different regulatory particles. Associated with two 19S regulatory particles, forms the 26S proteasome and thus participates in the ATP-dependent degradation of ubiquitinated proteins. The 26S proteasome plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins that could impair cellular functions, and by removing proteins whose functions are no longer required. Associated with the PA200 or PA28, the 20S proteasome mediates ubiquitin-independent protein degradation. This type of proteolysis is required in several pathways including spermatogenesis (20S-PA200 complex) or generation of a subset of MHC class I-presented antigenic peptides (20S-PA28 complex).
