title: Structure and chromosomal localization of the aminomethyltransferase gene (AMT)
abstract: The gene for human aminomethyltransferase (AMT), also known as the T-protein of the glycine cleavage system, was isolated from a human placental cosmid library and examined by restriction mapping, polymerase chain reaction analysis, and DNA sequencing. The gene is about 6 kb in length and consists of nine exons. The 5'-flanking region of the gene lacks typical TATAA sequence but has a single defined transcription initiation site detected by the primer extension method. Two putative glucocorticoid-responsive elements and a putative thyroid hormone-responsive element are present. The AMT gene was assigned to subband 3p21.2-p21.1 by fluorescence in situ hybridization.
