ICE1 encodes a bHLH protein. (A) Overall domain structure of ICE1 protein. A putative acidic domain (acidic), serine-rich region (S-rich), bHLH domain, and possible zipper region (ZIP) are indicated. The arrow indicates the amino acid residue changed in the ice1 mutant. (B) Sequence alignment of the bHLH domains and ZIP regions of ICE1 and other plant and animal bHLH proteins. Identical and similar residues are shown in black and gray, respectively. The basic region is indicated by a bold line and the helix–loop–helix domain is indicated by open boxes connected with a loop. The zipper region is indicated as a broken line. DDJB/EMBL/GenBank accession numbers, with amino acid numbers in parentheses, are: ICE1, AY195621 (300–398); At1g12860, NM_101157 (638–731); At5g65640, NM_125962.1 (171–269); At5g10570, NM_121095.2 (144–242); rd22BP, AB000875 (446–544); ATR2, NM_124046.1 (409–507); maize R gene, M26227 (410–508); TT8, AJ277509 (357–455); PIF3, AF100166 (254–352); PIF4, AJ440755 (255–353); MAX, P52161 (21–107); c-myc, 1001205A (354–435). Asterisks indicate amino acid residues of MAX that are known to interact with nucleotides (Grandori et al. 2000).
