STUB1 also known as CHIP (C-Terminal of Hsc70 Interacting Protein) is a protein with a molecular mass of approximately 35 kDa. It has ubiquitin ligase activity and functions as a co-chaperone. STUB1 interacts with chaperone proteins such as Hsp70 and Hsp90 modulating their activity. You can observe STUB1 expression in various tissues with higher levels found in the brain heart and skeletal muscle.
Biological function summary
STUB1 plays an important role in protein quality control by targeting misfolded or damaged proteins for degradation. It forms a complex with chaperone proteins Hsp70 and Hsp90 facilitating the ubiquitination process. This helps maintain cellular proteostasis. STUB1 has a critical role in preventing protein aggregation which is important in stress responses and normal cellular function.
Pathways
STUB1 has significant involvement in the protein degradation pathway and the heat shock response pathway. It works closely with proteasome-associated proteins to ensure proteostasis. In these pathways STUB1 interacts with other proteins such as Hsc70 and Hsp70 which assist in protein folding and stability under stress conditions.
STUB1 has links to neurodegenerative diseases and cancer. A dysfunction in STUB1 can lead to protein aggregation a hallmark of neurodegenerative conditions like Alzheimer's disease. In certain cancers altered STUB1 expression might affect cell survival pathways with related proteins including Hsp70 and Hsp90. Therapeutic strategies that modulate STUB1 and its interactions may provide avenues for disease intervention.
