Abstract: The identification, function and application of m6A methylation site in the FAM134B mRNA. The main steps include confirming the m6A methylation site in FAM134B mRNA by comparative analyzing m6A-seq results of Landrace and Jinhua pigs, corresponding with highly conserved motif RRACH (R=G, A; H=A, C, T) and the prediction website; altering the m6A methylation in FAM134B mRNA via mutating synonymous codon of FAM134B gene (C1358 to T1358) without changing the amino acid sequence; designing qPCR primers according to the m6A peak region and a control region of FAM134B mRNA; extracting total RNA and determining the relative m6A level of a single gene by protein immunoprecipitation and qPCR. The m6A methylation site of FAM134B mRNA plays a critical rule on fat deposition, which serves as a novel molecular marker and a drug target for treating obesity.
