In molecular biology, mir-281 microRNA is a short RNA molecule.
MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
mir-281 is found in an intron of the Drosophila ornithine decarboxylase antizyme (ODA) gene.
Using the RACE technique the pri-miRNA was shown to be 2,149 nucleotides in length.
