Abstract: The aim of this study was to clone and to identify the yak lncFAM200B, which might lay the foundation for exploring its regulatory role in yak muscle and fat during development. The primers for lncFAM200B gene were designed and used for the full-length cloning with the gluteal cDNA as template. The protein coding potential of lncFAM200B was predicted using the online prediction software CPC and CPAT, and then identified by prokaryotic expression assays. The tissue expression profile was analyzed by Real-time quantitative PCR (RT-qPCR), the target genes of miRNAs, which were interactions with lncFAM200B, were predicted by TargetScan 7.1 and miRanda. GO enrichment and KEGG pathway analysis were conducted with DAVID online software. The results showed that the full-length of yak lncFAM200B was 531 bp, which was 59 bp longer than that in cattle.Bioinformatics predicts results showed that its coding potential was -1.287 4, and prokaryotic expression assay further confirmed that lncFAM200B had no protein coding ability, suggesting that yak lncFAM200B was a real lncRNA. Tissue expression profiling showed that the expression of lncFAM200B had a higher level in yak lung tissue. The lncFAM200B interaction miRNA targets analysis revealed that many genes, such as Sirt1, SCD5, KLF9, PTEN and MYPN, were related to muscle and fat development.Taken together, the present study laid the foundation for further research on the function and regulatory mechanism of yak lncFAM200B in muscle and fat development.
