Statements

Type Excerpt DOI
Functional "Adaptive nonshivering thermogenesis (NST) of placental mammals is predominantly mediated by uncoupling protein 1 (UCP1), which resides at high levels in the mitochondrial inner membrane of brown adipose tissue (BAT) (1)." 10.1126/sciadv.1602878
Timing of Loss "Potential thermogenic limitations arising from UCP1 loss [as suggested for suids (25)] were clearly not an impediment to the ability of equines to exploit cold environments given “that Alaskan horses prospered during the LGM [last glacial maximum; ~18,000 years ago], and appear to have been particularly well adapted to the more intense versions of the cold/arid Mammoth Steppe (44)." 10.1126/sciadv.1602878

Curator Observations

A conserved premature Stop codon in exon 2 was observed in all Equus species analyzed (see fig. 1).
