Genes affected

RAD21 (HGNC:9811): (RAD21 cohesin complex component) The protein encoded by this gene is highly similar to the gene product of Schizosaccharomyces pombe rad21, a gene involved in the repair of DNA double-strand breaks, as well as in chromatid cohesion during mitosis. This protein is a nuclear phospho-protein, which becomes hyperphosphorylated in cell cycle M phase. The highly regulated association of this protein with mitotic chromatin specifically at the centromere region suggests its role in sister chromatid cohesion in mitotic cells.

UTP23 (HGNC:28224): (UTP23 small subunit processome component) Enables mRNA 3'-UTR binding activity and mRNA 5'-UTR binding activity. Predicted to be involved in rRNA processing. Predicted to act upstream of or within endonucleolytic cleavage in 5'-ETS of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be part of small-subunit processome. Predicted to be active in nucleolus. Implicated in colorectal adenocarcinoma. [provided by Alliance of Genome Resources, Apr 2022]

LOC112268030 (HGNC:):
