Zygosity genotype: Homozygous
This model expresses cre-recombinase under the control of the endogenous 5’- hydroxytryptamine receptor 3A (5Ht3a) promoter enabling specific expression in 5Ht3a positive serotonergic neurons. This model possesses a targeted insertion of (T2A)-cre immediately before the translational stop in the open reading frame of the 5Ht3a gene. The 5Ht3a-Cre rat is useful for applications requiring tissue specific expression, including optogenetics and breeding with transgenic floxed lines.
