| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Enables calcium ion binding activity involved in regulation of presynaptic cytosolic calcium ion concentration. Involved in intracellular calcium ion homeostasis; regulation of synaptic plasticity; and synaptic signaling. Located in dendriole and gap junction. Is active in parallel fiber to Purkinje cell synapse. Is expressed in several structures, including alimentary system; cranial mesenchyme; nervous system; reproductive system; and sensory organ. Orthologous to human CALB2 (calbindin 2). PHENOTYPE: Homozygous targeted mutants showed normal growth, normal brain histology, and generally normal behavior. Impaired motor coordination was observed in wheel running in young and old mutant mice, and progressive impairment was seen on the runway and horizontal stationary rod tests in older mice. Abnormalities are observed in Purkinje cell firing, altering both simple and complex spikes. [provided by MGI curators] |
