abstractText | Mouse prominin is the first characterized member of a novel family of membrane glycoproteins. It displays a characteristic membrane topology with five transmembrane segments and two large glycosylated extracellular loops. Prominin orthologues and paralogues have been identified in human, fish, fly, and worm. Recently, a cDNA sequence encoding the rat homologue of mouse prominin has been reported [Zhu et al. (2001) Biochem. Biophys. Res. Commun. 281, 951-956]. Surprisingly, due to a single nucleotide deletion that shifts the reading frame and introduces a premature stop codon, the protein predicted from this cDNA would correspond to a C-terminally truncated form of prominin with only four transmembrane segments. Here we report evidence that is in contrast to the report of Zhu et al. (2001). We isolated a rat prominin cDNA devoid of any frameshift mutation, demonstrate that rat prominin, like the other mammalian prominins, is a full-length 120-kDa pentaspan membrane glycoprotein, and have not been able to detect any C-terminally truncated form of rat prominin.
