Associated component of the proteasome that specifically recognizes acetylated histones and promotes ATP- and ubiquitin-independent degradation of core histones during spermatogenesis and DNA damage response. Recognizes and binds acetylated histones via its bromodomain-like (BRDL) region and activates the proteasome by opening the gated channel for substrate entry. Binds to the core proteasome via its C-terminus, which occupies the same binding sites as the proteasomal ATPases, opening the closed structure of the proteasome via an active gating mechanism. Component of the spermatoproteasome, a form of the proteasome specifically found in testis: binds to acetylated histones and promotes degradation of histones, thereby participating actively to the exchange of histones during spermatogenesis. Also involved in DNA damage response in somatic cells, by promoting degradation of histones following DNA double-strand breaks.

Proteasome Activator Subunit 4 (PSME4) also known as PA200 is an important component in regulating protein degradation. It belongs to the family of proteasome activator subunits and has a molecular mass of approximately 230 kDa. PSME4 is mainly expressed in the nucleus of cells and modulates proteasome activity by binding to the proteasome core particle. Through facilitating protein breakdown PSME4 significantly influences various cellular processes including the elimination of oxidatively damaged proteins.
PSME4 functions as part of a complex that enhances proteasome-mediated protein degradation. This complex formation improves the efficiency of protein processing by recruiting specific substrates for degradation. PSME4 is involved in DNA repair processes and plays a role in spermatogenesis contributing to proper cell cycle progression and genomic stability. The protein's activity in these biological functions demonstrates its importance in maintaining cellular homeostasis.
PSME4 is intricately involved in the ubiquitin-proteasome pathway and the DNA damage response pathway which are essential for maintaining protein quality control and genomic integrity. PSME4 interacts with other proteins such as RAD23B facilitating the repair of damaged DNA. By integrating into these pathways PSME4 ensures the proper execution of critical cellular processes and responds to stress-related signals.
Alterations in PSME4 expression or function have connections to cancer progression and neurodegenerative diseases. In cancer PSME4 may influence tumor growth and resistance to therapy through its role in DNA repair and protein turnover. Additionally in neurodegenerative conditions like Alzheimer's disease PSME4-associated proteasome dysfunction contributes to the accumulation of toxic protein aggregates. Understanding PSME4 interactions with proteins like p53 in cancer or tau in neurodegeneration offers insights into potential therapeutic targets.
