The deduced amino acid sequence of CK2α. (A) Sequence alignment of CK2α. Dots represent amino acids identical to the rice sequence. We identified amino acids conserved among 13 CK2α genes from 10 organisms other than plants; these are listed on the bottom row (marked “conserved”). Amino acids identical to the conserved one are boxed. Roman numerals indicate the 11 conserved subdomains of protein kinases (16). The arrow indicates the position of the premature stop codon in the Nipponbare allele. The following accession numbers reference the sequences used for the alignments: maize, Y11526; Arabidopsis, D10246. (B) The nucleotide sequence and the deduced amino acid sequence around the Nipponbare premature stop codon. The stop codon is changed to a lysine codon in the Kasalath allele.
