Supplementary information

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

SGTB also known as SGT2 is a co-chaperone protein with a molecular weight of approximately 35 kDa. It belongs to the small glutamine-rich tetratricopeptide repeat-containing and β-tubulin folding cofactor family. This protein is expressed in various tissues including the brain and liver. It interacts mechanically with other chaperones by forming complexes with HSP70 and HSP90 assisting in the folding and stabilization of client proteins.
Biological function summary

The co-chaperone activity of SGT2 facilitates essential cellular functions through its interaction with molecular chaperones. This protein plays a significant role in the protein quality control system within the endoplasmic reticulum (ER). SGT2 contributes to the functionality of the ER-associated degradation (ERAD) pathway by recognizing misfolded proteins destined for degradation. Through this action it supports cellular homeostasis and prevents the aggregation of misfolded proteins.

Pathways

SGT2 engages actively in the ERAD and heat shock response pathways. Within these pathways it works closely with chaperones like HSP70 and HSP90 to maintain protein quality control and cellular stress responses. SGT2 regulates the degradation of misfolded proteins which is important in the ERAD pathway for maintaining proteostasis. By coordinating with other co-chaperones SGT2 ensures the transfer of substrates to the ubiquitin-proteasome system therefore facilitating their removal and preventing cellular dysfunction.

SGT2's role in protein degradation links it to neurodegenerative diseases and cancer. In neurodegenerative diseases such as Alzheimer's disease the accumulation of misfolded proteins can result from dysfunctional protein degradation processes where SGT2 plays a role. Similarly alterations in SGT2 function could contribute to cancer as protein misfolding and degradation dysfunctions are often observed in tumor cells. In these disorders SGT2's interaction with chaperones like HSP70 and other components of the degradation pathways may become impaired disrupting cellular function and promoting disease progression.
