Organization and Complexity of the Yak (Bos Grunniens) Immunoglobulin Loci.

ABSTRACT: As important livestock in Qinghai-Tibet Plateau, yak provides meat and other necessities for Tibetans living. Plateau yak has resistance to diseases and stress, yet is nearly unknown in the structure and expression mechanism of yak immunoglobulin loci. Based on the published immunoglobulin genes of bovids (cattle, sheep and goat), the genomic organization of the yak immunoglobulin heavy chain (IgH) and immunoglobulin light chain (IgL) were described. The assemblage diversity of IgH, Igλ and Igκ in yak was similar to that in bovids, and contributes little to the antibody lineage compared with that in humans and mice. Somatic hypermutation (SHM) had a greater effect on immunoglobulin diversity in yak than in goat and sheep, and in addition to the complementarity-determining region (CDR), som
