Schematic diagrams of representative EF-hand proteins. The number of amino acids is given at the end of each diagram. Domain names are written above the domain except as given in the key. PI-PLC-X(Y) and C2, phosphatidylinositol-specific phospholipase C subdomains. ABI1, ABA-insensitive 1; APC1, Arabidopsis pollenCa²⁺-binding protein; AtCP1, Arabidopsis thaliana Ca²⁺-binding protein; AtFIM1, Arabidopsis thaliana fimbrin 1; AtPLC1, Arabidopsis thaliana phosphatidylinositol-specific phospholipase C; CAM2, calmodulin 2; CaBP22, 22 kd Ca²⁺-binding protein; CBL/SOS3, calcineurinB-like, salt-overly-sensitive protein; CH, calponin homology; CLO1, caleosin1; CPK, Ca²⁺-dependent protein kinase; CRK, CPK-related kinase; GDH2, NAD(H)-dependent glutamate dehydrogenase; GTPase, small GTPase-like protein (At3g63150); KCO1, potassium channel outwardly rectifying protein 1; KIC, KCBP-interacting CCD-1-like protein; MCP, mitochondrial carrier protein (At5g61810); PM129, protein isolated from plasma-membrane enriched library; PPA, protein phosphatase 2A-like protein (At1g03960); PYR, pyridine nucleotide-disulfide oxidoreductase (At2g20800); RbohA, respiratory burst oxidase homology; TCH2 and TCH3, touch-induced proteins. // indicates a break in the protein.
