Sequence Annotation Notes
DateNote
2004-01-07Based on comparison to related fungi, Brachat et al., Blandin et al., and Cliften et al. all proposed an intron and 5' extension for YBL091C-A. The resulting ORF is in the same frame with the start codon shifted 316 bp upstream; the protein has a 76-residue extension at the N-terminus.

1998-05-21The following 27 ORFs were added to the genome annotation based on Velculescu et al. 1997: YBL091C-A, YBL107W-A, YCR018C-A, YCR102W-A, YDL130W-A, YDR034C-A, YDR034W-B, YDR363W-A, YDR525W-A, YER048W-A, YER091C-A, YER138W-A, YGR122C-A, YIR020W-B, YKL033W-A, YKL053C-A, YKL162C-A, YLL018C-A, YLR262C-A, YML081C-A, YMR046W-A, YMR158C-B, YMR194C-A, YNR032C-A, YOL013W-A, YOR298C-A, and YPR002C-A.

The coordinates of the tag sequences along the genome were determined and each tag was classified into one of these four categories: 1) class 1 - within an existing ORF, 2) class 2 - within 500 bp downstream of existing an ORF, 3) class 4 - opposite of an existing ORF, or 4) class 3 - none of the above. The regions between two existing ORFs which contained one or more unique class 3 tags (number 4) above) were examined for potential coding sequences in which the unique tag was located either within the coding sequence or 500bp downstream of this sequence. BLASTP analysis was then performed for each potential ORF meeting these criteria against the non-redundant (nr) NCBI dataset, and those with a P value exponent of -6 or less were analyzed further. The BLAST results were analyzed on an individual basis for each potential ORF meeting the above criteria. Those potential ORFs which exhibited reasonable homology to other proteins, and did not appear to be matched with other proteins based on homology to repetitive sequences alone, were identified and entered into SGD.
