In this study, we analyzed the loci structure of raccoon dog genes using a comparative genomics approach. We investigated mechanism expression diversity and its preference Next-generation sequencing. The results indicated that gene were similar to most mammals, with relative abundance V(D)J genes, which ensures diversity. identified following potentially functional genes: 7 VH 6 Vκ 23 Vλ 24 DH 5 JH 4 Jκ Jλ arranged in manner other mammals. Analysis showed have strong for use V same was true genes. main modes recombination somatic hypermutation, high mutation region hypermutation not only concentrated CDR region, but also has FR types G > A, C T, T C, A G. Interestingly, compared differences between normal diseased dogs, there significant (P < 0.05), whereas no expression, utilization preference, recombination, types. summary, described IgH IgL dog, mapped loci, PE300 study could provide theoretical basis an in-depth understanding immunoglobulins, references disease-resistant breeding.

Immunoglobulins, a class of globulins with antibody properties, play crucial role in the body's defense against pathogens. In this study, we analyzed gene loci structure Silver-black fox using comparative genomics approach. The mechanisms expression diversity and its preferences were investigated through Next-generation sequencing (NGS). results revealed 32 potentially functional VH genes, 9 Vκ 17 Vλ DH 3 JH 6 Jκ 11 Jλ located on different scaffolds. Subsequently, 5'RACE PE300 bipartite used to obtain reads expressed repertoire foxes rearrangement events. analysis indicated strong preference use V genes J by fox. main ways V(D)J recombination somatic hypermutation (SHM). hypermutated region SHM was not only concentrated CDR but also had higher mutation rate FR region. types G > A, C T, T C, A G. findings study could serve as theoretical foundation for deeper understanding immunoglobulins, which is significant enriching knowledge immunogenetics providing support future studies vaccine design
