Associations Between Polymorphisms of the CSN1S1 , CSN1S2 , CSN2 and CSN3 Genes and Milk Composition Traits in Holstein Cattle [PDF]

Veterinary Medicine and Science
Background Caseins are the major proteins found in cow's milk. There are four known casein fractions: αS1‐casein, αS2‐casein, β‐casein and κ‐casein, encoded by the CSN1S1, CSN1S2, CSN2 and CSN3 genes located on the sixth chromosome of cattle. These genes

A novel duplex ACRS-PCR for composite CSN1S1–CSN3 genotype discrimination in domestic buffalo [PDF]

Italian Journal of Animal Science, 2021
This short communication aimed to develop a fast and straightforward method for the simultaneous discrimination in buffaloes of the alleles CSN1S1 A/B and CSN3 X1/X2 using a single protocol. DNA was isolated from 219 individual blood samples.

CSN1S1 and CSN3 genetic variants affect milk quality traits in the buffalo population in Serbia [PDF]

Journal of Animal Science and Technology
The Mediterranean water buffalo breed is the most common in Europe. Caseins are major milk proteins whose gene variants can affect milk yield, composition, and processing characteristics.

A hypomorphic mutation in the mouse Csn1s1 gene generated by CRISPR/Cas9 pronuclear microinjection [PDF]

Вавиловский журнал генетики и селекции, 2021
Caseins are major milk proteins that have an evolutionarily conserved role in nutrition. Sequence variations in the casein genes affect milk composition in livestock species.

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

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.

Effect of α_s1-casein (CSN1S1) genotype on milk CSN1S1 content in Malagueña and Murciano-Granadina goats [PDF]

Journal of Dairy Research, 2008
There is substantial evidence showing that the polymorphism of the goat αs1-casein (CSN1S1) gene has a major effect on milk protein, casein and fat content as well as on cheese yield. However, its influence on the synthesis rate of CSN1S1 has been less studied, with measurements only available in French breeds.

CSN1S1 and CSN3 gene variants in female Murrah buffaloes in the Brazilian Amazon [PDF]

Anais da Academia Brasileira de Ciências, 2022
The characteristics of milk are controlled by several genes, with emphasis on the four genes from casein, CSN1S1; CSN1S2; CSN2 and CSN3, which are responsible encoding of fractions the milk protein.

Investigation of a Rare CSN1S1⁰¹ Allele in Goats Using Allele-Specific PCR and Mathematical Expectation Analysis [PDF]

Animals
The casein alpha s1 (CSN1S1) gene plays an important role in milk protein synthesis and has been associated with milk quality and calcium-related physiological processes in mammals. To date, 19 CSN1S1 variants have been reported. Among them, the CSN1S101

Comparative analysis of gene sequence of goat CSN1S1 F and N alleles and characterization of CSN1S1 transcript variants in mammary gland

Gene, 2005
In this paper, we report the full characterization, at DNA and RNA level, of the defective goat CSN1S1 F and N alleles and an extensive comparison with the A allele counterpart. By utilizing genomic DNA as template, we amplified the whole CSN1S1 gene plus 1972/3 nucleotides of the 5' region plus 610 nucleotides of the 3' region of the goat CSN1S1 N and
