Family of microRNA precursors
miR-144 is a family of microRNA precursors found in mammals , including humans . The ~22 nucleotide mature miRNA sequence is excised from the precursor hairpin by the enzyme Dicer .[ 1] In humans, miR-144 has been characterised as a "common miRNA signature"[ 2] of a number of different tumours .
GATA4 is thought to activate transcription of the miR-144 microRNA precursor.[ 3]
Function
miR-144 functions in a cluster with miR-451 . This locus regulates the expression of a number of genes whose products are involved in erythropoiesis .[ 4] One of the identified targets of miR-144 is insulin receptor substrate 1 .[ 5]
Applications
miR-144 has been identified as one of a number of potential miRNA targets which could be used to treat schizophrenia and bipolar affective disorder .[ 6] It has also been suggested as a potential therapeutic tool to treat ischemic heart disease .[ 3]
