additional information | construction of transgenic mice that express an skeletal muscle-MLCK, i.e. skMLCK, CaM biosensor in skeletal muscle to determine whether skMLCK or calmodulin is limiting to twitch force potentiation. Three transgenic mouse lines exhibited up to 22-fold increases in skMLCK protein expression in fast-twitch extensor digitorum longus muscle containing type IIa and IIb fibers, with comparable expressions in slow-twitch soleus muscle containing type I and IIa fibers, overview | Oryctolagus cuniculus |
