Abstract:
:Dopamine D4 receptor (DRD4) has received attention in terms of pathogenesis of schizophrenia and association with human personalities. We isolated the human DRD4 gene containing the 5'-flanking region and determined its sequence. Analysis of the DRD4 transcripts by 5'-RACE (5'-rapid amplification of cDNA ends) revealed a region of the transcription initiation located between -501 and -436 relative to the first nucleotide of the initiation codon. There is a CpG island spanning from -900 to +500 but no TATA or CAAT boxes in the 5'-flanking region. Functional analysis of the 5'-flanking region of the DRD4 gene by a transient expression method revealed the presence of a negative modulator between -770 and -679. The region between -591 and -123 gave the highest transcriptional activity in IMR32 (neuroblastoma) and Y-79 (retinoblastoma) cells but not in HeLa cells, suggesting that this housekeeping gene-like promoter regulates the cell-type specific gene expression.
