Comparison of the predicted amino acid sequences of <i>HSFY</i> in Hereford and Holstein cattle.

<p>The mRNA sequences are 99% homologous and differ by only one base pair (c.1192A>C). This missense substitution mutation (p.<i>Tyr266Ser</i>) results in an amino acid change from tyrosine (Y) in Hereford to serine (S) in Holstein in the predicted protein sequence (shown by the box). This mutation is not found in the conserved HSF-type DNA-binding domain which is shown by the underlined sequence.
