Primary structure of three minor isoforms of amphioxus sarcoplasmic calcium-binding proteins.
Previously we reported the amino acid sequences of 4 well-defined sacroplasmic, high-affinity Ca(2+)-binding proteins in the protochordate amphioxus, Branchiostoma lanceolatum [1]. Here we report on the complete amino acid sequence determination of 3 additional minor isoforms. The seven isoforms differ from each other in 9 positions of a contiguous 17-residue-long segment (positions 20-36) and can be classified in a alpha (ASCP I, III and IV) and a beta lineage (ASCP II, V, VI and VII).
