Immunoglobulin genomics in the guinea pig (Cavia porcellus).

ABSTRACT: In science, the guinea pig is known as one of the gold standards for modeling human disease. It is especially important as a molecular and cellular biology model for studying the human immune system, as its immunological genes are more similar to human genes than are those of mice. The utility of the guinea pig as a model organism can be further enhanced by further characterization of the genes encoding components of the immune system. Here, we report the genomic organization of the guinea pig immunoglobulin (Ig) heavy and light chain genes. The guinea pig IgH locus is located in genomic scaffolds 54 and 75, and spans approximately 6,480 kb. 507 V(H) segments (94 potentially functional genes and 413 pseudogenes), 41 D(H) segments, six J(H) segments, four constant region genes (μ, γ, ε, and
