Fig. 6. Expression of the larger parvalbumin isoform, Parv1, relative to total parvalbumin content (expressed as a proportion). Values (mean ± s.e.m.) are given for 7 body positions for all sheepshead muscle types and three body positions for red muscle of kingfish. In sheepshead and kingfish red muscle, there is a significant longitudinal shift in parvalbumin expression, with a higher proportion of Parv1 in the posterior swimming muscle. There is also a similar pattern of Parv1 content in the other sheepshead muscle fiber types but this is not statistically significant. N=6 (sheepshead red muscle), 4 (kingfish red muscle and sheepshead white muscle), 3 (sheepshead pink muscle).
