Genes marked by a asterisk were not assigned numbers during annotation. c Designation of gene locus on annotated bacterial artificial chromosome. D Indicates whether gene is expressed, based on cloned cDNA (see Note for reference) or presence of cognated EST or full length cDNA. e Numbers of amino acids in variable domain. f Number of EF hands predicted by SMART (Shultz et al., 1998) and by sequence aligment (Fig. 2). g The first 8 amino acids at N-terminus of the CDPKs. hThe prediction of Myristoylation motif is based on PROSITE program (Hoffmann et al., 1999) with considerations drew from Towler et al. (1988), Ellard-Ivey et al. (1999), Martin and Busconi (2000), Lu et al.,(2001), and Raices et al. (2001). i Subcellular distribution. j 1, Harper et al., 1993; 2, Hrabak et al., 1996; 3, Hong et al., 1996; 4, Urao et al., 1994; 5, Willmann et al., unpublished; 6, Harmon et al., 2001."
