Mir-22
In molecular biology mir-22 microRNA is a short RNA molecule. MicroRNAs are an abundant class of molecules, approximately 22 nucleotides in length, which can post-transcriptionally regulate gene expression by binding to the 3’ UTR of mRNAs expressed in a cell. == Origins == Mir-22 was originally identified in HeLa cells (an immortal cell line derived from cervical cancer cells), but was later found to be ubiquitously expressed in various tissues. The gene encoding miR-22 is found on the short arm of chromosome 17, in a minimal loss of heterozygosity region. It is highly conserved across many vertebrate species, including chimp, mouse, rat, dog and horse. This level of conservation suggests functional importance. MiR-22 was previously identified as having a role in erythrocyte maturation.
