Abstract
Due to two different polyadenylation signals, two forms of S-adenosylmethionine decarboxylase (AdoMetDC) mRNA (2.1 and 3.4 kb) are present in human and rodent tissues. The nucleotide sequences of rat and human cDNAs corresponding to the shorter mRNA were published previously by us [Pajunen et al., J. Biol. Chem. 263 (1988) 17040-17049]. These sequences covered the coding regions but were incomplete at their 5' ends. Here we report the sequence of rat cDNA spanning the entire longer mRNA with a substantially extended leader region, and compare the sequence with that of a rat psi AdoMetDC pseudogene isolated from a rat genomic library. Relative to the mRNA, the pseudogene has multiple base changes as well as insertions, and deletions. Furthermore, it lacks introns, and is flanked by a short direct repeat. These are typical characteristics of a processed retrogene.Entities:
