Comparative testis proteome dataset between cattleyak and yak

AbstractCattleyak are hybrid between cattle and yak, which exhibit equivalent adaptability on the Qinghai-Tibetan Plateau as yak and much higher capability in economic traits. However, the F1 males of cattleyak are infertile due to spermatogenic arrest and this greatly restricts the effective utilization of this hybrid. In this data article, differentially expressed proteins (DEPs) were identified from testis proteome of cattleyak and yak using high-performance liquid chromatography–electrospray tandem mass spectrometry (LC–ESI-MS/MS). All the DEPs were subjected to functional classification by Gene Ontology (GO) analysis and gene-pathway annotation by Kyoto Encyclopedia of Genes and Genomes (KEGG). The comparative testis proteome dataset here can shed new light on the molecular characteristics of male infertility of cattleyak on proteome level, “Comparative iTRAQ proteomics revealed proteins associated with spermatogenic arrest of cattleyak” [1]
