The central 5-hydroxytryptamine ( Serotonin, 5-HT ) system play an
important role in the brain sexual differentiation in tilapia,Oreochromis
mossambicus. ¡@The 5-HT1A receptor is involved in the neural develop-
ment of brain.¡@The cDNA sequences of 5-HT1A receptor of tilapia, Ore-
ochromis mossambicus have been cloned in our laboratory.¡@In the
present study, 1633 bp of DNA sequence of 5-HT1A receptor from the
transcription start site ( TSS ) were cloned by 5¡¦ rapid amplification of
cDNA end ( 5¡¦ RACE ) and Genome Walker DNA Walking.¡@The 1633
bp of DNA sequence divided into six different fragments to detect the
luciferase activity in the HeLa cell.¡@The bioinformatic analysis was
performed on the fragment which showed the highest luciferase activity
for predicting the transcription factor binding site.¡@These results showed
that there is a activator protein-1 ( AP-1 ) binding site in the fragment
form -52 bp to -46 bp.¡@The site-direct mutagenesis and electrophoresis
mobility shift assay was performed on the fragment form -52 bp to -46 bp
.¡@The present results indicate that there is a transcription factor binding
site in the fragment form -52 bp to -46 bp.¡@This transcription factor
binding site could be a AP-1 binding site.
