DateNote
2007-06-01Please note that in the UMass snoRNA database, the sequence listed for the U3a snoRNA (snR17a) differs from that listed in SGD at one nucleotide. SGD lists a C at relative position 357, while UMass currently lists this nucleotide as a G. The UMass numbering below reflects relative coding coordinates with the intron removed; SGD numbering below reflects relative coding coordinates before the removal of the intron.

The SGD reference sequence is based on that received from the European yeast chromosome XV sequencing project, based on S288C substrain FY1679, as listed in GenBank records Z75144 and Z75143. The SGD sequence also matches GenBank records M18578 from strain JRY117 (Bachellerie 1989) and X05499 from strain BY4743 (Hughes et al. 1987). The UMass record matches GenBank record M26648 from strain BY4741 (Myslinski et al. 1990).

Mapping Notes
DateNote
1992-10-01Edition 11: snR17a is adjacent to dfr1; the 3' end of snR17a is 311 bp from the 5' end of dfr1

1998-11-10Edition 15: In the past this locus was incorectly identified as another name for the YOR235W locus, which snr17a overlaps. snr17a encodes the untranslated U3 small nuclear RNA gene, and YOR235W is a predicted open reading frame (ORF) of 104 amino acids for which there is presently no experimental evidence.
