Tg(1.4dlx5a-dlx6a:GFP)ot1

About

Tg(1.4dlx5a-dlx6a:GFP)ot1 larvae express GFP in subpallial neurons γ-aminobutyric acid (GABA)-expressing neurons. Several other brain regions also show GFP expression in this transgenic line such as the optic tectum and cerebellum.
 

 Dlx homeobox genes play essential roles in the differentiation, migration and survival of subpallial precursor cells that will later give rise to diverse subtypes of γ-aminobutyric acid (GABA)-expressing neurons. They also participate in the regulation of the Gad genes encoding the enzymes necessary for GABA synthesis (Yu et al., 2011).

Et(fos:Gal4-VP16)s1168t

About

 This transgenic originates from Herwig Baier’s laboratory and is one of many enhancer trap Gal4 lines created by them. Driving Kaede expression in the posterior tuberculum,hypothalamus and cerebellum. There is a very interesting tract labelled that projects between the midbrain tegmentum and posterior tuberculum. The tract skirts the tectal neuropil. The insertion of this transgene is currently unmapped.

pku2Et/ ETvmat2:GFP

About

 Synonyms: Et(gata2a:EGFP)pku2, Et(gata2a:GFP)zf81, pku2Et, ETvmat2:GFP

The ETvmat2:GFP transgenic zebrafish line was identified from a large scale enhancer trap screen (unpublished data (Wen et al., 2008)) using a Tol2 vector containing a 249 bp zebrafish gata2 minimal promoter linked to a GFP reporter gene. (Wen et al., 2008). The enhancer trap vector was inserted in the second intron of vmat2 gene with the transcription direction of the GFP reporter opposite to that of the vmat2 gene (Wen et al., 2008).

This enhancer trap line recapitulates the expression pattern of vmat2 and labels most monaminergic neurons in the zebrafish. Vesicular monoamine transporter 2 (Vmat2) is a monoamine transporter VMAT2 is a membrane protein that transports monoamines, including neurotransmitters such as dopamine, norepinephrine, serotonin, and histamine from the cytosol into synaptic vesicles.
