GeneDescription Htr1aa is a 5-hydroxytryptamine receptor that is expressed in the raphe nuclei, retina, medulla oblongata, paraventricular organ, pretectal diencephalic complex and caudal zone of the periventricular hypothalamus, in line with the expression profiles of homologues.
GeneFunction Airhart et al. (2007) examined the effect of selective serotonin reuptake inhibitor (SSRI), fluoxetine (PROZAC), on the ontogeny of spontaneous swimming activity (SSA) in developing zebrafish. They detected the potential changes in SERT and HT1A receptor transcripts in 6 dpf larvae after a 24 h exposure to 4.6 μM fluoxetine on 5 dpf. Three regions of CNS were inidividually analysed, two defined brain regions, and spinal cord. The brain regions showed no effect on transcript levels after exposure to fluoxetine, but spinal cord showed decrease in both transcripts.Norton et al. (2008) compared the expression of 5-HT transporter genes slc6a4a and slc6a4b, and three 5-HT receptors, htr1aa, htr1ab, and htr1bd. From the analysis of serotonin transporter (SERT)- encoding genes they identified parallel genetic pathways that are used to build the 5-hydroxytryptamine system in Zebrafish. The receptors showed their expression in both the larval and adult brain. By comparing the expression of transporter and receptor genes they mapped the sites of autoreceptor activity within the brain.
GeneCloning Htr1a is contained in the BAC clone named DKEY-250L23 (library: Daniokey; Vector: pIndigoBAC-536).
GeneStructure The gene encodes for a single transcript ENSDART00000138217 which consists of a single exon and is 1,786 bps in length. The protein product (ENSDARP00000121666) consists of 398 residues.
