Mir-281 microRNA precursor family explained

mir-281
Symbol:	mir-281
Rfam:	RF00967
Mirbase Family:	2
Rna Type:	microRNA
Tax Domain:	Eukaryota

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. The expression level of the microRNA was found to be independent of the level of ODA.^[1]
