Mitochondrial complex I deficiency increases PSMB9 mRNA levels and proteasome activity.a RNA-seq analysis of 20 S (left panel) and 19 S (right panel) proteasome components gene expression log2 fold changes (log2FC) in mitochondrial complex I-deficient HEK293T cells compared to WT HEK293T cells (n = 4). Up- and down-regulated genes (q-value < 0.05) are shown in green and pink, respectively. An immunoproteasome subunit is shown in blue. The intensity of the color shades depends on the level of expression change. Gray indicates genes with not statistically significant expression changes. b mRNA expression patterns of selected transcripts validated by RT-qPCR. The mRNA levels are presented as fold changes relative to WT. Data shown are mean ± SD (n = 3 biological replicates with two technical replicates). p-value from an ordinary one-way ANOVA with Dunnett's multiple comparisons test using GraphPad Prism. c Chymotrypsin-like and caspase-like proteasome activities in cell lysates presented as fold changes relative to WT.

PSMD1 also known as Proteasome 26S Subunit Non-ATPase 1 plays a mechanical role in protein degradation within cells. It is a component of the 26S proteasome complex which is responsible for degrading ubiquitinated proteins. The molecular mass of PSMD1 is approximately 108 kDa. PSMD1 expresses broadly in various tissues including the liver heart and skeletal muscle suggesting its involvement in basic cellular functions.
Biological function summary

PSMD1 contributes to the regulation of protein homeostasis through its function in the 26S proteasome complex. This multi-protein complex enables the ATP-dependent degradation of ubiquitinated proteins a critical process for maintaining cellular function. The proteasome's activity ensures the removal of damaged or misfolded proteins and regulates concentrations of specific proteins to maintain cellular processes. Its interaction with other proteasome subunits indicates a strong functional integration within this complex.

Pathways

PSMD1 plays a role in the ubiquitin-proteasome pathway a major pathway for protein catabolism. This pathway is critical for various cellular processes including cell cycle regulation and apoptosis. PSMD1 interacts with other subunits in the proteasome such as PSMA1 and PSMB5 to execute its function. Its connection to these pathways highlights its importance in regulating protein turnover and quality control in cells.

PSMD1 has relevance to cancer and neurodegenerative diseases. Dysregulation of the ubiquitin-proteasome pathway wherein PSMD1 is a significant component can lead to aberrant protein accumulation contributing to disease conditions. In cancers altered PSMD1 expression impacts cell proliferation and survival linking it indirectly with tumor-related proteins such as p53. Similarly in neurodegenerative diseases impaired proteasome function involving PSMD1 associates with proteins like tau known for their role in disorders like Alzheimer's disease.

Target data

Component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. This complex plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins, which could impair cellular functions, and by removing proteins whose functions are no longer required. Therefore, the proteasome participates in numerous cellular processes, including cell cycle progression, apoptosis, or DNA damage repair.
