Information from provider
Provider | Markus Missler |
Provider affiliation | Department of Anatomy and Molecular Neurobiology, Westfälische Wilhelms-University Münster |
Genetic information | A neo cassette replaced the first exon, which contains the complete 5' UTR, start codon, signal peptide and the first LNS (Laminin alpha, Neurexins, and Sex hormone-binding globulin) domain. Immunoblotting of mutant brain confirmed lack of protein. |
Phenotypic information | Mice homozygous for a knock-out allele show a 30-40% decrease in body weight and their inhibitory postsynaptic currents (IPSCs) are decreased in cortical slice cultures. |
Breeding history | Backcrossed for 8 generations to C57BL/6J. |
