Remarks:
Hypothetical mRNA sequence of NDST1 assembled in silico by two-step multiple sequence alignment polished by
manual editing. First, EST sequences matching the cloned 5'-UTR region from mouse skin, brain and testis (and
deposited to GenBank under GI:21780279, 418bp) were aligned and resulting 5'-UTR region consensus sequence
partly overlapping to ORF region was created. The ORF overlapping sequence was used to find NDST1 protein
records, and their mRNA sequences were aligned to the consensus sequence created previously. The final
consensus sequence is this hypothetical mRNA. Please note several EST were longer at the 5'-end while having
different alignment in largers blocks (could be different exons). Therefore, the actually cloned sequence by
Grobe was only extended at the 5'-end using the sequence from highly similar sequences.
For consensus sequence of 5'-UTR were used records GI# 16490862, 11492647, 21780282 (the one published by
Grobe et al., 2002), 16484896, 16464127. For consensus sequence of ORF and 3'-UTR were used records GI#
71043952, 50927496, 12854230.
The sequence deposited in IRESite is the final consensus sequence but was trimmed at the 3'-end from poly(A)
sequence.
