| Genetic information | The murine Dagla gene is located at chromosome 19 and comprises 20 exons. In the Dagla-tm1.2Zim (Dagla knock-out) line the exon 1 was removed by cre recombinase-mediated excision (the floxed strain used is EMMA strain EM:14881). Depiction of the cloning and knock-out strategy is shown at Fig. 1 in Jenniches et al., Biol. Psychiatry, 2015. |
| Phenotypic information | Homozygous:The Dagla-tm1.2Zim homozygous knock-out line is epilepsy prone, spontaneous epileptic seizures are observed especially in stress situation. The body weight of the mice is lower than in wild-type littermates from a heterozygous breeding. The behavioral changes induced by Dagla deletion include a reduced exploration of the central area of the open field, a maternal neglect behavior, a fear extinction deficit, increased behavioral despair, increased anxiety-related behaviors in the light/dark box, and reduced hippocampal neurogenesis. Heterozygous:Heterozygous mice were not tested. |
| Breeding history | 10 generations on C57BL/6J. |
