Remarks:
Hypothetical mRNA sequence of NDST4L assembled in silico by two-step multiple sequence alignment polished by
manual editing. First, EST sequences matching the cloned 5'-UTR region from brain and embryonic (and deposited
to GenBank under GI:21780283, 669bp) were aligned and resulting 5'-UTR region consensus sequence
partly overlapping to ORF region was created. The ORF overlapping sequence was used to find NDST4 protein
records, and their mRNA sequences were aligned to the consensus sequence created previously. The final
consensus sequence is this hypothetical mRNA. The NDST4S variant has shorter 5'-UTR region as it is
transcribed from a promoter P2 located in 5'-UTR of this NDST4L variant (Fig. 1) consisting of CAAT and TATA
boxes (5'-CAAT-GTGTG-TATAAAT-3').
For consensus sequence of 5'-UTR were used records GI# 26415164, 21780283 (the one published by Grobe et al.,
2002), 17092388, 27141716, 16482267, 32466133. For consensus sequence of ORF and 3'-UTR was used record
GI:12000418.
