This gene encodes a protein containing a nuclear localization signal and an S-adenosyl-L-methionine binding motif typical of methyltransferases, suggesting that the encoded protein may act on DNA methylation. This gene is deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternatively spliced transcript variants have been found.,BUD23,HASJ4442,HUSSY-3,MERM1,PP3381,WBMT,WBSCR22,Epigenetics & Nuclear Signaling,Cancer,Signal Transduction,Endocrine & Metabolism,Amino acid metabolism,WBSCR22
