ABSTRACT Human β-galactosidase precursor mRNA is alternatively spliced into an abundant 2.5-kb transcript and a minor 2.0-kb species. These templates direct the synthesis of the classic lysosomal β-D-galactosidase enzyme and of a β-galactosidase-related protein with no enzymatic activity. Mutations in the β-galactosidase gene result in the lysosomal storage disorders GM1-gangliosidosis and Morquio B syndrome. To analyze the genetic lesions underlying these syndromes we have isolated the human β-galactosidase gene and determined its organization. The gene spans >62.5 kb and contains 16 exons. Promoter activity is located on a 236-bp Pst I fragment which works in a direction-independent manner. A second Pst I fragment of 851 bp located upstream from the first negatively regulates initiation of transcription. The promoter has characteristics of a housekeeping gene with GC-rich stretches and five potential SP1 transcription elements on two strands. We identified multiple cap sites of the mRNA, the major of wh...
