We assessed polymorphisms in exon IV of the kappa-casein gene (CSN3) in ten different breeds of domestic goat (Capra hircus) from three continents and in three related wild caprine taxa (Capra ibex, Capra sibirica and Capra aegagrus). Thirty-five DNA samples were sequenced within a 558 bp fragment of exon IV. Nine polymorphic sites were identified in domestic goat, including four ...

NF-kappa B is an important transcription factor required for T cell proliferation and other immunological functions. The NF-kappa B1 gene encodes a 105-kD protein that is the precursor of the p50 component of NF-kappa B. Previously, we and others have demonstrated that NF-kappa B regulates the NF-kappa B1 gene. In this manuscript we have investigated the molecular mechanisms by which T cell lin...

Quantitative RT-PCR analysis. The following primers were used to amplify β-casein cDNA and 18S rRNA sequences: forward primer of the β-casein gene 5'-GCT CAG GCT CAA ACC ATC TC-3' and reverse primer 5'-TGT GGA AGG AAG GGT GCT AC-3'; forward primer of the 18S rRNA gene 5’-TCGGAACTGAGGCCATGATT-3’ and reverse primer 5’CCTCCGACTTTCGTTCTTGATT-3’. Fragments of β-casein gene and 18S rRNA were amplifie...

Casein genes directly control milk protein of animals. CSN1S1 (αS1-Casein) and CSN2 (β-Casein) influence on fractions. Genetic polymorphisms gene at g.12164G>A locus g.8913C>A were identified by PCR-RFLP technique. Animal samples pure dairy goats providing PE (5 hds.), Saanen (8 hds.) their crosses Sapera (50% Saanen, 50% PE) (51 SaanPE (75% 25% (3 from IRIAP goat station. Allele frequenc...

Background: The variants of β-casein (CSN 2) gene viz. A1 and A2 are supposed to be related with human health. Hence, know the status breeding bulls used for AI services were screened variants. Total 47 blood samples crossbred from Frozen Semen Laboratory, Pune Aurangabad present work. Methods: extraction genomic DNA by phenol-chloroform method carried out bulls. Further, based PCR-RFLP was ide...

This work evaluated the angiotensin-converting-enzyme (ACE)-inhibitory activities of a bovine sodium caseinate fermentate generated using the proteolytic capabilities of the porcine small intestinal isolate Lactobacillus animalis DPC6134 (NCIMB deposit 41355). The crude 10-kDa L. animalis DPC6134 fermentate exhibited ACE-inhibitory activity of 85.51% (+/-15%) and had a 50% inhibitory concentrat...

The GCS1 gene of the budding yeast Saccharomyces cerevisiae mediate the resumption of cell proliferation from the starved, stationary-phase state. Here we identify yeast genes that, in increased dosages, overcome the growth defect of gcs1 delta mutant cells. Among these are YCK1 (CK12) and YCK2 (CKI1), encoding membrane-associated casein kinase I, and YCK3, encoding a novel casein kinase I isof...

The objective of this study was to estimate the effects of beta-kappa-casein (CN) haplotypes on first-lactation milk production traits. The beta-kappa-CN haplotypes were deduced using information on beta- and kappa-CN genotypes of cows and their sires for 16,973 Finnish Ayrshire cows that had at least nine paternal half sibs. Effects of CN haplotypes on milk production traits were estimated for...

The influence of cortisol and prolactin on casein gene expression in the mammary gland of lactating BALB/c mice was measured by using a specific cDNA probe to 15S casein mRNA (cDNAcsn). Casein mRNA (mRNAcsn) level in the mammary gland was decreased by 85% 5 days after adrenal ablation, but then was increased 4.4-fold 12 hr after a single injection of hydrocortisone-21-acetate. An 80% decrease i...
