Molecular cloning of two species of cDNAs for human alpha-N-acetylgalactosaminidase and expression in mammalian cells

Biochem Biophys Res Commun. 1990 Jul 16;170(1):231-7. doi: 10.1016/0006-291x(90)91264-s.

Abstract

Two species of cDNAs for human alpha-N-acetylgalactosaminidase were isolated from a human fibroblast cDNA library. The two species differ each other by a 70 bp insertion in the coding region. Transient expression study in COS cells demonstrated that only the cDNA without the 70 bp insertion expressed alpha-N-acetylgalactosaminidase activity. Analysis of mRNA species utilizing polymerase chain reaction revealed that the majority of the mRNA does not contain the 70 bp insertion, and the mRNA containing the 70 bp insertion is present only in a minor amount in human brain.
