glutathione s-transferases (gsts) are a major family of detoxification enzymes which possess a wide range of substrate specificities. interest in insect gsts has primarily focused on their role in insecticide resistance. in this study, following world health organization (who) routine susceptibility test, dna was extracted from specimens of anopheles stephensi collected from the kazeroon distri...

b-lactoglobulin (Coded by the b-lg gene) is the major milk whey protein in ruminants. Studies have shown that this protein is polymorphic in many breeds of sheep as a result of a single base pair substitution in the b-lg gene that also gives rise to RsaI restriction fragment length polymorphism (RFLP). Blood samples were collected from 391 animals belonging to 5 Iranian and 6 Russian sheep bree...

Note: 6 exons, spread out over approximately 2.4 kb Description The Rac3 gene encompasses 6 exons on chromosome 17. Exon 1 encodes residues 1-12, exon 2 residues 1336, exon 3 residues 37-75, exon 4 residues 76-96, exon 5 residues 97-149 and exon 6 residues 150-192. Transcription Human Rac3 mRNA is a single species of around 1 kb. No splice variants have been reported. Factors that would regulat...

The complete structure of a quail fast skeletal muscle troponin I gene was determined by nucleotide sequence comparison of troponin I genomic and cDNA sequences. This 4.5-kilobase troponin I gene has eight exons. The actin-binding domain of troponin I is encoded by a single exon, whereas the troponin C-binding domain is split into at least two exons. The exon organization of the fast troponin I...

Background: Pre-eclampsia is a multifactorial pregnancy specific vascular disorder characterized by hypertension and proteinuria. It affects around 3-5% pregnancies worldwide. The aetiology and pathophysiology of PE remain poorly understood. But it is generally accepted defective placentation during the early stage of pregnancy most likely in combination with maternal and environmental factors ...

Stearoyl-CoA desaturase (SCD) is a rate-limiting enzyme in the biosynthesis of monounsaturated fatty acids (MUFA). A number of studies support the hypothesis that SCD gene regulation and polymorphism may affect fatty acid composition and fat quality in meat and milk. Single nucleotide polymorphisms in the coding region of the bovine stearoyl-CoA desaturase gene have been predicted to result in ...

the κ-casein protein plays a fundamental role in milk production and its composition synthesis in the mammary gland. this protein has an important role in the formation, stabilization, and aggregation of the casein micelles. in this study, we investigated the genetic variability at the exon 4 of the κ-casein gene (also known as csn3) using pcr-sscp analysis and dna sequencing. then a protein se...
