The second yak peptide represents the last peptide (14 amino acids), which allows for the identification of Bos grunniens/mutus (BLG-E) (36). Here we compare the sequences from several key dairy animals (cattle, yak, sheep, and goat) to demonstrate the increasing sequence differences as species diverge phylogenetically. Accession codes in UniProt for BLG A is P02754 (shown in UniProt as Bos taurus), and BLG E is L8J1Z0 (shown in UniProt as Bos mutus).
