Detection of two CSN1S1 variants in Egyptian buffalo [PDF]

Journal of Genetic Engineering and Biotechnology, 2013
AbstractThe present study investigates CSN1S1 casein gene polymorphism in Egyptian buffalo. CSN1S1 was analyzed in 17 unrelated Egyptian lactating buffalo. The amplified segment includes the last 43 amino acids of Exon 17 and part of Intron 17. In the present study we report for the first time the presence of 2 variants 178Ser (TCA) and 178Leu (TTA) in

Genetic polymorphism of CSN1S1 and CSN2 loci in Rossa Mediterranea goat population [PDF]

Italian Journal of Animal Science, 2010
The αs1(CSN1S1) and β (CSN2) casein loci were investigated in Rossa Mediterranea, a dairy goat population reared in Sicily, in order to identify the most important quantitative alleles.

Genotyping at the CSN1S1 locus by PCR-RFLP and AS-PCR in a Neapolitan goat population [PDF]

Small Ruminant Research, 2008
Abstract The goat CSN1S1 gene has for many years been an excellent model for demonstrating that most of the variability observed in the αs1-casein content in goat's milk is due to the presence of autosomal alleles at a single structural locus . Until now, about 17 alleles associated to at least four levels of αs1-casein expression in milk have ...

Evaluation of the α-casein (CSN1S1) locus as a potential target for a site-specific transgene integration

Scientific Reports, 2022
Transgenic animals are an important tool in biotechnology, including the production of recombinant proteins in the milk. Traditionally, expression constructs are based on hybrid vectors bearing mammary gland specific regulatory elements from the α-casein

Mediterranean river buffalo CSN1S1 gene: search for polymorphisms and association studies [PDF]

Animal Production Science, 2014
The aim of the present study was to investigate the variability at CSN1S1 locus of the Italian Mediterranean river buffalo and to study possible allele effects on milk yield and its composition. Effects of parity, calving season and month of production were also evaluated. Three single-nucleotide polymorphisms were detected. The first mutation, located

Lama glama αS1-casein: Identification of new polymorphisms in the CSN1S1 gene [PDF]

Journal of Dairy Science, 2017
South American camelids have been poorly genetically investigated and little information is available in llamas (Lama glama) regarding the diversity of the caseins at the protein and gene level. Exon skipping and duplication events previously reported in the αS1-casein gene (CSN1S1) led us to investigate the genetic variability at this locus.

Goat Milk with Different Alpha-s1 Casein Genotype (CSN1S1) Fermented by Selected Lactobacillus paracasei as Potential Functional Food [PDF]

Fermentation, 2019
The characteristics of fermented milk are affected by the type of milk used and the microorganisms involved in the fermentation process. Goat milk has been widely suggested as a possible alternative to cow milk in allergic subjects, because of the high ...

MiR-2284b regulation of α-s1 casein synthesis in mammary epithelial cells of dairy goats [PDF]

Animal Biotechnology
The lactation character of dairy goats is the most important characteristic, and milk protein is an important index to evaluate milk quality. Casein accounts for more than 80% of the total milk protein in goat milk and is the main component of milk ...
