| abstractText | Meprin, a glycoprotein with potent metalloendopeptidase activity, is an integral component of the brush border membrane of mouse kidney. Previously we reported that genealogically related inbred mouse strains (C3H and CBA) are markedly deficient in the activity of this enzyme. We report here that meprin deficiency is inherited as an autosomal recessive trait and that several other inbred strains also express low levels of meprin activity. All of the inbred strains deficient in meprin activity are of the H-2k haplotype; however, two strains of this haplotype (C58 and C57BR/cd) expressed normal levels of the proteinase. Congeneic and recombinant mouse strains were examined to determine whether the deficiency was linked to the H-2 complex. The gene controlling the activity of meprin (Mep-1) maps on chromosome 17 to the right of the D end of the major histocompatibility complex. The Mep-1 gene is closely linked to a gene that controls isoenzyme patterns of phosphoglycerate kinase (Pgk-2). This work represents the localization of a gene that determines the activity of an integral cellular endopeptidase in mammalian tissues. In addition, the Mep-1 gene is the only identified gene linked to the major histocompatibility complex that regulates a proteinase activity. |
