Summary
Two novel alleles, BoLA-DRB3-P*06 and BoLA-DRB3-P*07, were discovered in the upstream regulatory region of the BoLA-DRB3 gene. These findings expand the known genetic diversity of cattle immune response genes.
Area of Science:
- Genetics
- Immunology
- Veterinary Science
Background:
- The BoLA-DRB3 gene plays a crucial role in cattle immune responses.
- Understanding genetic variations in its regulatory regions is vital for livestock breeding and disease resistance.
Purpose of the Study:
- To identify and characterize new alleles in the upstream regulatory region of the BoLA-DRB3 gene.
- To contribute to the understanding of BoLA-DRB3 genetic diversity.
Main Methods:
- Analysis of the 228-bp nucleotide sequences of the promoter region.
- Identification of regulatory boxes including W, X, Y, CAAT, and TATA.
Main Results:
- Two new alleles, BoLA-DRB3-P*06 and BoLA-DRB3-P*07, were identified.
- BoLA-DRB3-P*06 has an insertion between W and X boxes and a transition between X and Y boxes.
- BoLA-DRB3-P*07 has an insertion within the X box.
Conclusions:
- The discovery of these new alleles enhances the known allelic repertoire of the BoLA-DRB3 promoter.
- These variations may influence gene expression and cattle immune function.
