Isolation of dopamine D-2 receptor (D2R) promoters in Mugil cephalus

This paper reports the isolation of two putative D2R promoters from grey mullet, one 5' flanking and the other an intronic sequence immediately upstream of the first coding exon. Promoter activity of the intronic sequence was confirmed in vitro through functional analysis using luciferase as reporter gene. The functional characteristics of the region flanking the 5'-UTR is currently under investigation.
