Abstract : miRNA binding sites in the mRNA nucleotide sequences of 247 transcription factor (TF) genes of Bos taurus ZNF family was established. miRNAs binding sites are located in the 5'UTRs, CDSs and 3'UTRs of mRNAs. miRNA binding sites in mRNAs were selected with the value ΔG/ΔGm equal or greater than 85%. miR-574 was identified from 749 Bos taurus miRNAs, it has binding sites with mRNAs of KLF7, SNAI2, WIZ, ZFP1, ZFP91-1, ZNF175, ZNF6772, ZSCAN29-1 genes. The value ΔG/ΔGm varied from 85 to 95%. The starts of miR-574 binding sites with mRNAs of KLF7, ZFP91-1, ZNF6772 genes are located through two nucleotides. miR-574 binding sites are located in the 3'UTR. miR-1260b has binding sites with mRNAs of 29 genes (BCL11B-1, CTCF-1, DPF2-1, EGR3, FEZF2, PRDM13, PRDM14, PRDM6, SALL1, SP6-2, SP8, WIZ, ZFX-1, ZFX-2, ZKSCAN1, ZNF219, ZNF335, ZNF341, ZNF384, ZNF48, ZNF513, ZNF618-1, ZNF653, ZNF668, ZNF746, ZNF75, ZNF805, ZNF774, ZSCAN20-1) which are located in the 3'UTRs, CDSs and 5'UTRs. The value ΔG/ΔGm varied from 85 to 91%. The starts of miR-1260b binding sites in mRNAs of ZNF618-1 target gene are located through one nucleotide in the 5'UTR and with mRNAs of ZNF384, BCL11B-1 genes through three nucleotides in the CDSs. We found miR-2881, miR-2882, miR-2885, miR-3141 and miR-6528 binding sites in the nucleotide sequences of mRNAs of 27, 17, 23, 40 and 21 target genes, respectively. The value ΔG/ΔGm for these miRNAs varied from 85 to 96%. We also established binding sites for families of miRNAs: miR-1777 (miR-1777a, miR-1777b), miR-2284 (miR-2284aa, miR-2284b, miR-2284c, miR-2284f, miR-2284h-5p, miR-2284i, miR-2284l, miR-2284m, miR-2284o, miR-2284p, miR-2284s, miR-2284v, miR-2284z), miR-2285 (miR-2285ae, miR-2285af, miR-2285g, miR-2285o, miR-2285p, miR-2285q, miR-2285, miR-2285w, miR-2285y) and miR-2325 (miR-2325a, miR-2325c) with mRNAs of Bos taurus ZNF family TF genes.
