parvalbumin	Rattus norvegicus (Norway rat)	genetic evidence of involvement in relaxation of muscle after contraction: Transfection of muscle cells with the cDNA for wildtpye parvalbumin significantly reduced the half-relaxation time for muscle twitch, while transfection with the cDNA for a mutant parvalbumin unable to bind calcium had not effect on the half-relaxation time.
