Genes affected

STUB1 (HGNC:11427): (STIP1 homology and U-box containing protein 1) 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.

STUB1 links:

JMJD8 (HGNC:14148): (jumonji domain containing 8) Involved in several processes, including positive regulation of I-kappaB kinase/NF-kappaB signaling; positive regulation of sprouting angiogenesis; and regulation of glycolytic process. Located in endoplasmic reticulum lumen and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
