Parvalbumins are found in the muscles, endocrine glands, skin cells, and some neurons of vertebrates, but the role they play for musculature is not yet understood. Researchers are exploring theories of a correlation between parvalbumin concentration levels and the relaxation speed of mammalian muscles after contraction. An ultra-high resolution structure was achieved from samples grown on STS-83 and in July 1997, during STS-94, PCAM produced the largest crystals of pike parvalbumin grown to date.
