Sequence Annotation Notes
DateNote
2003-09-22Based on the automated comparison of closely related Saccharomyces species, Kellis et al. suggest that the start site for ATG4/YNL223W be moved 36 nt (12 codons) downstream. This suggestion was reviewed and accepted by SGD curators. The numbering for both the nucleotides in the DNA coding sequence and the amino acids in the predicted protein have been changed accordingly. Evidence supporting this change includes: 1) This is the predicted start methionine in the majority of Saccharomyces species orthologs analyzed by Kellis et al. and/or Cliften et al.; 2) Significant sequence conservation begins abruptly at this predicted start methionine; 3) The first ATG is not conserved in S. paradoxus, S. mikatae, and S. bayanus; 4) In an independent Genbank record also uses the second ATG for the protein translation (Version AAA86498.1 GI:1173491).
