There are a number of ELISA Kits available for the measurement of DNA methyltransferase 3B, another term for the human protein, DNA methyltransferase 3 beta. Other synonyms may include: DNA (cytosine-5)-methyltransferase 3B, DNA (cytosine-5-)-methyltransferase 3 beta, DNA MTase HsaIIIB, DNA cytosine-5--methyltransferase 3 beta, ICF, ICF1, and M.HsaIIIB. It is encoded by the DNMT3B gene to yield a protein 853 amino acids in length and 95.8 kDa in size. However, there are up to 8 reported isoforms. The protein, an enzyme, is categorized into the Class I-like SAM-binding methyltransferase superfamily, C5-methyltransferase family. Versions of DNA methyltransferase 3B are present in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
