mir-711 microrna precursor family mir-711 microrna precursor family in molecular biology mir-711 microrna is a short rna molecule. micrornas function to regulate the expression levels of other genes by several mechanisms. mir-711identifierssymbolmir-711rfamrf01923 mirbase familymipf0000748other datarna typemicrornadomain(s)eukaryota;pdb structurespdbe diagnostic use in cutaneous t-cell lymphoma mir-711 is able to distinguish between malignant cutaneous t-cell lymphomas and benign skin disorders with high accuracy. hsp70.3 and further regulation mir-711 has been found to target and suppress heat shock protein 70.3 in vitro at a post-transcriptional level via its 3' untranslated region. ischaemic preconditioning brings about reduced mir-711 levels, with downregulated cardiac myocyte levels further dependent upon nf-kappa b.
