glyt2b- FISH

About glyt2b (synonyms: slc6a5)

glycine transporter 2/ Solute Carrier Family 6 (Neurotransmitter Transporter), Member 5

glyt2b is orthologous to human GLYT2/ slc6a5 . This gene encodes a sodium- and chloride-dependent glycine neurotransmitter transporter. This protein is found in glycinergic axons and glycinergic synapses. Glycine is a major inhibitory neurotransmitter in the central nervous system of vertebrates.

Expression pattern

glyt2b is expressed in glycinergic neurons in the hindbrain.

sst1.1- FISH

About sst1.1

somatostatin 1

sst1 is orthologous to human SST, somatostatin . This gene encodes a peptide hormone that modulates neurotransmission. Zebrafish have 6 different somatostatin genes.

---

Expression pattern

sst1.1 is expressed in the habenula, neurosecretary pre-optic area NPO, subpallium, preoptic area, posterior tuberculum, ventral thalamus, hypothalamus, interpeduncular nucleus, medulla oblongata.

tac3a- FISH

About tac3a

tachykinin precursor 3a
synonyms: Neurokinin B

tac3a is orthologous to human TAC3 and in rodents to tac2. TAC3/Neurokinin B may participate in neuroendocrine control of zebrafish reproduction by stimulating gonadotropin-releasing hormone (GnRH) neurons, mainly via kisspeptin. In mammals, NeurokininB is coexpressed with kisspeptin (Kiss) and dynorphin in neurons of the arcuate nucleus of the hypothalamus, which are therefore called KNDy neurons

---

Expression pattern

At embryonic and larval stages tac3a is expressed asymmetrically in the dorsal habenula. tac3a mRNA-expressing cells detected in the subpallium (SubP), posterior tuberculum(PT) , rostral and intermediate hypothalamus, posterior tuberal nucleus (PTN), tegmentum(Teg), superior raphe (SR) and the medulla oblongata.
