Abstract:
Our data demonstrate the presence of a naturally occurring family of alleles in the core promoter of the 5-LO gene, which is characterized by the deletion or addition of consensus Sp1 (-GGGCGG) and Egr-1 (-GCGGGGGCG-) binding motifs. Each of the variant alleles can bind Sp1 and Egr-1 protein, as indicated by EMSA and supershift analysis with nuclear extracts. In addition, preliminary data from CAT reporter assays indicate that these alleles are less effective than the wild-type allele in initiating 5-LO gene expression. Whether patients harboring the various alleles identified herein have different capacities to transcribe the 5-LO gene and the importance of such potential regulation to the clinical expression of 5-LO have yet to be determined.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Protein Import into the Peroxisomes
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
