IRESite record type: plasmid_with_promoter_and_putative_IRES_translationally_characterized
The shape of the nucleic acid molecule translated: linear
The quality of the mRNA/+RNA sequence: hopefully_full-length_mRNA
The mRNA/+RNA description:
Putative in vivo transcript from CMV promoter of pCAT-NDST4L-delta100-eGFP including the SV40 early poly(A)
signal. 112 bp were deleted on the 3'-end of the putative NDST4L IRES.
The mRNA/+RNA sequence represented in the +DNA notation:
Credibility of mRNA sequence: end-to-end_sequence_reverse_engineered_and_should_match_experiment
The description of the protein encoded in this ORF: enahnced green fluorescent protein
The translational frameshift (ribosome slippage) involved: 0
The ribosome read-through involved: no
The alternative forms of this protein occur by the alternative initiation of translation: not tested
The ORF absolute position (the base range includes START and STOP codons or their equivalents): 1374-2093
Remarks:
NDST4 is transcribed from two different promoters. The longer NDST4L and shorter NDST4S share only partially
the first exon (432bp vs. 140bp), and completely share the second exon. The upstream promoter is TATA-less.
The downstream promoter includes CAAT/TATA box 77/68 bases upstream the transcription start site and is
located in the first cistron. Total lengths of 5'-UTRs are 669 and 377bp. See Fig. 1 in Grobe and Esko (2002).
The splice sites in all NDST variants are A(G/G)TAAGT...intron...CA(G/N).
A region of the first exon shared by both NDST4L and NDST4S is similar to htrp3 mRNA 5'-UTR region:
