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[edit]

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[edit]

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]
