abstractText | Genetic variation of a carboxylesterase isozyme (EC 3.1.1.1) of the house mouse, designated ES-23, is described. ES-23 was found in kidney, liver, and intestine. The isozyme was resistant to inhibition by 10(-3) mol/liter eserine and was stained using alpha-naphthyl butyrate or 5-bromoindoxyl acetate as substrate. Five different phenotypes, ES-23A to ES-23E, could be distinguished by disc electrophoresis and by isoelectric focusing. ES-23 is controlled by a structural locus situated within the esterase gene cluster 2 on chromosome 8. An analysis of allele distribution among different strains suggested a separate structural locus for the isozyme, Es-23e, which is closely linked to the loci Es-2, Es-5, Es-7, and Es-11. Of the five phenotypes, only ES-23B was expressed in lung. This variation is apparently controlled by a cis-acting regulatory element, presumably a temporal locus, Es-23t, closely linked to the presumed structural locus Es-23e. |
