| Functional | "Hair follicle-specific keratin genes consisted of 9 hair follicle-specific epithelial keratin genes (K71-K75, K25-K28) and 17 hair keratins (K31-K40, K81-K86) expressed in hair follicle and hair which could directly affect hair growth." | 10.1186/s12983-017-0225-x |
| 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 [...] bowhead whale (Balaena mysticetus, coverage 150×, http://www.bowheadwhale.org/downloads/)." | 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 the gene 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.
