Annotation Changes without sequence changes
| Date | Affected Features |
|---|---|
| 2014-11-19 | ARS911, ARS912, ARS913, ARS914, ARS920, ARS922, ARS923 As part of SGD's genome annotation revision R64.2, new ARS consensus sequences were annotated within the following ARS elements on Chromosome IX based on Liachko et al. 2013: ARS911, ARS912, ARS913, ARS923, ARS914, ARS920, ARS922. |
| 2014-11-19 | ARS909, ARS913, ARS914, ARS919, ARS922, ARS923 The chromosomal coordinates of the following ARS elements on Chromosome IX were updated based on Liachko et al. 2013 as part of SGD's genome annotation revision R64.2: ARS909, ARS913, ARS923, ARS914, ARS919, ARS922. |
| 2014-11-19 | ARS907 ARS907 was added to the genome annotation based on Liachko et al. 2013 as part of SGD's genome annotation revision R64.2. |
| 2014-11-19 | YIR043C, YIR044C The annotations of YIR043C and YIR044C, which were previously annotated as adjacent pseudogenes, have been changed as part of SGD's genome annotation revision R64.2. They were merged into a single blocked reading frame, keeping the name YIR043C. YIR044C is being retained as an alias. |
| 2014-11-19 | YIL167W, YIL168W As part of SGD's genome annotation revision R64.2, the annotations of SDL1/YIL167W and YIL168W, which were previously annotated as adjacent pseudogenes, have been changed. They were merged into a single blocked reading frame, keeping the name SDL1/YIL167W. YIL168W is being retained as an alias. |
| 2013-08-14 | YIL080W YIL080W was included in the original annotation in error and was later withdrawn because it overlaps completely with functional transposable element gene YIL082W-A. It was annotated with the same start as YIL082W-A, but with a different stop codon 225 bp downstream, resulting in an incorrectly appended C-terminus containing internal stops. |
| 2010-01-05 | PWR1 New ncRNA PWR1 was added to the genome annotation based on Bumgarner et al. 2009. |
| 2010-01-05 | ICR1 New ncRNA ICR1 was added to the genome annotation based on Bumgarner et al. 2009. |
| 2009-05-07 | ARS902, ARS904, ARS910, ARS915, ARS918, ARS921 The following ARS elements on Chromosome 9 were added to the genome annotation based on Raveendranathan et al. 2006: ARS902, ARS904, ARS910, ARS915, ARS918, and ARS921. |
| 2007-04-04 | YIL123W SIM1/YIL123W mRNA contains an intron in the 5' untranslated region (UTR). |
| 2007-04-03 | YILWdelta2 YILCdelta2, a Ty2 LTR on Chromosome IX, was mistakenly annotated on the wrong strand (i.e., on Crick instead of Watson). Both the orientation and the feature name have been corrected, so that the LTR now has the systematic name YILWdelta2 and is annotated on the Watson strand. Thanks go to Bertrand Llorente for bringing this annotation error to our attention. The name YILCdelta2 is being retained as an alias. |
| 2006-10-03 | ARS923 ARS923, also known as ARS913.5, was added to the genome annotation based on Nieduszynski et al. 2006. |
| 2006-09-08 | ARS909, ARS911, ARS912, ARS914, ARS919, ARS920, ARS922 The following new ARS elements on Chromosome IX were added to SGD based on Nieduszynski et al. 2006: ARS909, ARS911, ARS912, ARS914, ARS919, ARS920, ARS922. |
| 2006-09-08 | ARS913 The coordinates of ARS element ARS901, also known as ARS913, were updated based on Nieduszynski et al. 2006. |
| 2006-05-09 | CEN9 The previously annotated 3' boundary of CEN9 was moved 1 bp upstream to coincide with the 3' end of CDEIII, to more accurately reflect current knowledge regarding centromere structure in Saccharomyces cerevisiae. |
| 2006-01-24 | YIL053W Based on 5' SAGE transcription start site data and experimental verification of the start methionine, the start site for YIL053W was moved 63 bp downstream. As a consequence, YIL053W was shorted on the 5' end, altering the N-terminus and shortening the size of the predicted protein from 271 amino acids to 250 amino acids. |
| 2006-01-23 | YIL043W Based on based on 5' SAGE TSS data, Zhang and Dietrich suggest that the start site for CBR1/YIL043C be moved 114 nt (38 codons) downstream. These data corroborate the start site that Kellis et al. predicted based on the alignment of multiple orthologous sequences. This change has been incorporated into SGD and the numbering for both the nucleotides in the DNA coding sequence and the amino acids in the predicted protein have been changed accordingly. |
| 2005-11-22 | YIL076W Based on 5' SAGE transcription start site data and experimental verification of the start methionine, the start site for YIL076W was moved 189 bp downstream. As a consequence, YIL076W was shortened on the 5' end, altering the N-terminus and shortening the size of the predicted protein from 359 amino acids to 296 amino acids. |
| 2005-11-21 | YIL102C-A Based on comparisons of the genome sequences of six Saccharomyces species, Cliften et al. 2003 suggested that this new ORF, YIL102C-A, be added to the S. cerevisiae genome annotation. |
| 2004-10-12 | CEN9 Centromeric DNA elements CDEI, CDEII, and CDEIII were annotated based on Wieland et al. 2001 and Espelin et al. 2003. |
| 2003-09-27 | YIL073C Based on the alignment of orthologs in related Saccharomyces species, Cliften et al. proposed an intron and new 5' exon for SPO22/YIL073C. The resulting ORF is in the same frame, but has an 89-residue extension at the N-terminus. This change was reviewed and accepted by SGD curators. |
| 2003-09-22 | YIR014W The automated comparison of closely related Saccharomyces species suggests that the start site for YIR014W be moved 102 nt (34 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. |
| 2003-09-22 | YIL145C Based on the automated comparison of closely related Saccharomyces species, Kellis et al. suggest that the start site for PAN6/YIL145C be moved 108 nt (36 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. |
