miR-338 is a family of brain-specific microRNA precursors found in mammals, including humans. The ~22 nucleotide mature miRNA sequence is excised from the precursor hairpin by the enzyme Dicer. This sequence then associates with RISC which effects RNA interference. miR-338 is located in an intronic region within the gene for apoptosis-associated tyrosine kinase (AATK). It has been predicted that it may downregulate genes which have a downstream negative effect on AATK expression.
