| Abstract: | In comparative-evolutionary aspect, the experimental data are considered about activity, biochemical properties, and peculiarities of structural organization of proteins of the calpain family in some invertebrates and fishes. Peculiarities of calpain-like proteins of invertebrates--the predecessors of calpains of higher animals are revealed. By the example of the studied taxons, there is traced complication of the structural organization and mechanisms of control of the calpain activities, which reflects stages of molecular evolution of the protein family. |
