Summary: This gene encodes a protein containing tetratricopeptide repeat and a U-box that functions as a ubiquitin ligase/cochaperone. The encoded protein binds to and ubiquitinates shock cognate 71 kDa protein (Hspa8) and DNA polymerase beta (Polb), among other targets. Mutations in this gene cause spinocerebellar ataxia, autosomal recessive 16. Alternative splicing results in multiple transcript variants. There is a pseudogene for this gene on chromosome 2.

TEAD activity is tightly controlled through the regulation of palmitoylation and stability via the orchestration of FASN, depalmitoylases, and E3 ubiquitin ligase in response to cell contact.
Title: Cell contact and Nf2/Merlin-dependent regulation of TEAD palmitoylation and activity.
Data indicated that STUB1 deficiency leads both to the intracellular accumulation of protein aggregates and to an increase in the secretion of small extracellular vesicles (sEVs), including exosomes. Secreted sEVs are enriched in ubiquitinated and/or undegraded proteins and protein oligomers. Also, oxidative stress induces an increase in the release of sEVs in cells depleted from STUB1.
Title: Exosomes and STUB1/CHIP cooperate to maintain intracellular proteostasis.
Study reports that STUB1 regulates gastric cancers (GC) cell proliferation and response to therapeutic drugs through YAP1. STUB1 is responsible for YAP1 ubiquitination at K280 and degradation. Downregulation of STUB1 promoted GC proliferation, tumorigenesis, and chemoresistance in a YAP1-dependent manner. STUB1 expression inversely correlates with YAP1 in GC, suggesting a role for the STUB1-YAP1 axis in GC pathogenesis.
Title: STUB1 suppresseses tumorigenesis and chemoresistance through antagonizing YAP1 signaling.
Phosphatase PGAM5 (phosphoglycerate mutase 5) and deubiquitinase OTUB1 (ovarian tumor domain containing ubiquitin aldehyde binding protein 1) were confirmed as E4B substrates, and beta-catenin and CDK4 (cyclin-dependent kinase 4) were confirmed as CHIP substrates.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
