subsequently degraded or altered during myosin. If the latter role is confirmed, then it normal postmortem aging. Studies that have is also possible that nebulin’s postmortem used antibodies against titin have been shown degradation may alter actin-myosin interac- to cease to recognize T2 after prolonged tions in such a way that the alignment and periods of postmortem storage or μ-calpain interactions of thick and thin filaments in digestion (Ho et al. 1994; Huff-Lonergan postmortem muscle is disrupted. This, too, et al. 1996a) could lead to an increase in postmortem ten- derization. Nebulin degradation does seem to be correlated to postmortem tenderization, Nebulin
