Genes affected
OIP5 (HGNC:20300): (Opa interacting protein 5) The protein encoded by this gene localizes to centromeres, where it is essential for recruitment of CENP-A through the mediator Holliday junction recognition protein. Expression of this gene is upregulated in several cancers, making it a putative therapeutic target. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]
OIP5-AS1 (HGNC:43563): (OIP5 antisense RNA 1) This is a conserved gene that produces a long non-coding RNA that maintains cell proliferation in embryonic stem cells. This RNA can bind to and negatively regulate the activity of multiple cellular RNAs and microRNAs, including cyclin G associated kinase and ELAV like RNA binding protein 1. [provided by RefSeq, Dec 2017]
