The description of the protein encoded in this ORF: enhanced 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): 1233-1952
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:
