Meltrin beta (ADAM19) gene: cloning, mapping, and analysis of the regulatory region

Abstract

Meltrin beta (ADAM19) is a member of the metalloprotease-disintegrin family. We report here chromosomal mapping of the mouse and rat meltrin beta genes and cloning and analysis of the mouse upstream regulatory regions. The meltrin beta transcript shows a spatially and temporally restricted expression pattern during morphogenesis, indicating that the actions of this membrane-bound protease are regulated, at least in part, at the transcriptional level. Analysis of the promoter revealed positive and negative regulatory regions upstream of the gene. The former includes a GC-box that appears to be a critical cis-element for activation of the promoter in muscle cells.
