Strain Information

BRC No.RBRC00408
TypeTargeted Mutation CongenicCartagena
SpeciesMus musculus
Strain nameB6.129P2-Gfap<tm1Ito>/ItoRbrc
Former Common nameGfap KO, GFAP-KO-clone 27
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strainC57BL/6JJcl
Strain developmentDeveloped by Shigeyoshi Itohara, Institute for Virus Research, Kyoto University in 1995. The construct was electoroporated into E14 ES cells derived from 129P2/OlaHsd. The mutant mice were backcrossed to C57BL/6J.
Strain descriptionGfap knockout mice. Immediately downstream of the endogenous start codon of Gfap was replaced with a cassette, containing a promoterless lacZ and pgk-neo. Gfap, glial fibrillary acidic protein is an intermediate filament protein specifically expressed in astrocytes. Homozygous mutant mice develop normally and not show any detectable abnormalities in the anatomy of the brain. But, exhibit a impairment of long-term depression (LTD) and PF-Purkinje cell synapses and eyeblink, suggested that the Gfap is required for communications between Bergmann glia and Purkinje cells.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]. Homozygous mutant mice are viable and fertile.
