Predicted to enable enzyme binding activity and guanyl-nucleotide exchange factor activity. Acts upstream of or within several processes, including learning or memory; maternal behavior; and maternal process involved in parturition. Predicted to be located in several cellular components, including neuronal cell body; nucleoplasm; and perinuclear region of cytoplasm. Predicted to be active in several cellular components, including glutamatergic synapse; postsynaptic density; and presynapse. Predicted to be extrinsic component of membrane. Is expressed in cerebral cortex ventricular layer; cortical plate; dorsal root ganglion; and spinal cord. Human ortholog(s) of this gene implicated in cerebral atherosclerosis; cerebral infarction; and coronary artery disease. Orthologous to human KALRN (kalirin RhoGEF kinase).
MGI Description
PHENOTYPE: Mice homozygous for a knock-out allele specific for isoform 7 exhibit decreased anxiety-related behavior, contextual conditioning, and synapse formation. Mice homozygous for another knock-out allele exhibit impaired AMPA-mediated synaptic currents and abnormal behavior. [provided by MGI curators]
