| Methodology & Validation | "We first identified α-keratin gene repertoires in the cow (Bos taurus) (coverage 7×,Btau_4.6.1) [...] taking all the known α-keratin gene sequences of human as queries using BLASTN and TBLASTN algorithm. [...] The putative α-keratin genes in the cow were then taken as queries to explore the α-keratin multigene family in the genome of 11 marine mammals, including [...] Yangtze River dolphin (Lipotes vexillifer, Lipotes_vexillifer_v1, coverage 115×, NCBI)." | 10.1186/s12983-017-0225-x |
| Phenotypic | "Our results show an apparent reduction in the α-keratin gene repertoire and increased rate of pseudogenization in cetaceans when compared to terrestrial counterparts, which may be associated with their hairless phenotype." | 10.1186/s12983-017-0225-x |
Curator Observations
The authors named the keratins according to the human nomenclature. Gene not found in genomic maps-gene deletion (Fig1). This gene loss is likely to be Cetacea-specific according to the papers' data; however, as the authors don't provide sequence information.
