RT "Trypanosoma rangeli and Trypanosoma cruzi: molecular characterization of
RT genes encoding putative calcium-binding proteins, highly conserved in
RT trypanosomatids.";
RL Exp. Parasitol. 84:387-399(1996).
CC -!- FUNCTION: May contribute to the rapid motility of the trypanosomes,
CC playing a role either in flagellar structure or in calcium metabolism.
CC Could alternate between a GDP-bound inactive form to a calcium/GTP-
CC bound active form.
CC -!- SUBCELLULAR LOCATION: Cell projection, cilium, flagellum.
CC -!- DOMAIN: This protein has four EF-hand domains, three of which may be
CC functional calcium-binding sites.
CC -!- SIMILARITY: Belongs to the calflagin family. {ECO:0000305}.
