There are a number of ELISA Kits available for the measurement of DNA methyltransferase 3A, another term for the human protein, DNA methyltransferase 3 alpha. Other synonyms may include: DNA (cytosine-5)-methyltransferase 3A, DNA (cytosine-5-)-methyltransferase 3 alpha, DNA MTase HsaIIIA, DNA cytosine methyltransferase 3A2, M.HsaIIIA, and TBRS. It is encoded by the DNMT3A gene to yield a protein 912 amino acids in length and 101.9 kDa in size. However, there are up to 3 reported isoforms. The protein, an enzyme, is categorized into the Class I-like SAM-binding methyltransferase superfamily, C5-methyltransferase family. Versions of DNA methyltransferase 3A are present in other organisms, including: Mouse, Rat, Frog, Chicken.
