RA Takagi T., Konishi K.;
RT "Amino acid sequence of the beta chain of sarcoplasmic calcium binding
RT protein (SCP) obtained from shrimp tail muscle.";
RL J. Biochem. 96:59-67(1984).
CC -!- FUNCTION: Like parvalbumins, SCPs seem to be more abundant in fast
CC contracting muscles, but no functional relationship can be established
CC from this distribution.
CC -!- SUBUNIT: SCPs from crayfish, lobster, and shrimp are polymorphic
CC dimers; three isotypes (alpha-alpha, alpha-beta, and beta-beta) have
CC been identified.
CC -!- MISCELLANEOUS: The sarcoplasmic calcium-binding proteins are abundant
CC in the muscle of arthropods, mollusks, annelids, and protochordates.
CC -!- MISCELLANEOUS: This protein has three functional calcium-binding sites;
CC potential site 4 has lost affinity for calcium.
