Characterization of three new members of the Arabidopsis thaliana calmodulin gene family: conserved and highly diverged members of the gene family functionally complement a yeast calmodulin null.

Abstract excerpt

Three genes encoding members of the EF-hand family of Ca2+-binding proteins were identified from Arabidopsis thaliana (L.) Heynh. sequences deposited in the expressed sequence tag and genomic sequence databases. Full-length cDNAs for each of the genes, Cam7, Cam8, and Cam9, were sequenced. Cam7 encodes a conventional 16.8-kDa, 148-amino-acid calmodulin protein (CaM). In contrast, Cam8 and 9 encode highly diverged...
