None: Hydroxyindole-O-methyltransferase (HIOMT) catalyzes the last step in the synthesis of the pineal hormone melatonin. In this study, an HIOMT clone was isolated from a human pineal cDNA library using synthetic oligonucleotide probes based on the bovine HIOMT sequence. The human sequence is unusual because it contains a 3' fragment (84 bp) of the LINE-1 sequence, a highly repetitive sequence in the human genome and the genome of some primates and rodents. Exclusive of this LINE-1 fragment, the human HIOMT clone is 75% and 63% homologous to bovine and avian HIOMT sequences, respectively. The deduced amino acid sequence of the human cDNA clone encodes a 41.6-kD...
