| 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 [...] bottlenose dolphin (Tursiops truncatus, coverage 30×, Ttru_1.4, UCSC)." | 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. Authors consider this gene to be a pseudogene, with no further explanation or sequence information provided. As such, the gene loss mechanism is inconclusive. This gene loss is likely to be Cetacea-specific according to the papers' data; however, as the authors don't provide sequence information.
