[Signal function of calcium-binding proteins in lower eukaryotes].

This review summarizes data on the signaling role of calcium-binding proteins (CaBP) in lower eukaryotes cells. The contributions of calmodulin (CaM)-like proteins, calcium-dependent protein kinases (CDPK), as well as calcineurin B-like phosphatase (CaNB) and some other proteins to Ca(2+)-dependent regulation of cellular functions is considered.
