From: Sp1/3 and NF-1 mediate basal transcription of the human P2X1 gene in megakaryoblastic MEG-01 cells
Sequence of the P2X 1 proximal promoter region. Potential transcription factor binding sites are underlined and in bold. Oligonucleotide sequences used for primer extension analysis (Pet1-4) are indicated by horizontal arrows. End points of plasmid deletion constructs in this region are indicated by "p" and number above the sequence. Sequence numbering is relative to the transcription start site indicated as +1. The translation initiation ATG is boxed. The EMBL/Genbank accession number of this sequence is AJ971536.
