pku2Et/ ETvmat2:GFP

pku2Et/ ETvmat2:GFP


 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The ETvmat2:GFP transgenic zebrafish line was identified from a large scale enhancer trap screen (unpublished data (Wen et al., 2008)) using a Tol2 vector containing a 249 bp zebrafish gata2 minimal promoter linked to a GFP reporter gene.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.
