Alignment of the predicted amino acid sequences derived from the caprine KAP1-2 gene sequences and ovine KAP1-2 variant A. The prefix “g” and “s” stand for goat and sheep sequences, respectively. The dashes indicate identity with caprine KAP1-2*C and the dots represent amino acid deletions. The decapeptide ‘QTSCCQPT(S/C)X’ repeats are boxed, and pentapeptide ‘CEPTC’ repeats are shaded. The levels of cysteine (21.7–23.1%) and serine (15.3–15.8%) were high, while the content of threonine (9.6–11.5%), proline (9.6–9.9%), glutamine (8.3–9.6%) and glycine (8.2–9.6%) was moderate in the predicted polypeptide sequences encoded by caprine KRTAP1-2.
