Primary Identifier | MGI:87961 | Organism | mouse, laboratory |
Chromosome | 4 | NCBI Gene Number | 11603 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables several functions, including chondroitin sulfate binding activity; heparan sulfate proteoglycan binding activity; and transmembrane transporter binding activity. Involved in several processes, including negative regulation of sodium ion transmembrane transport; positive regulation of Rac protein signal transduction; and positive regulation of protein modification process. Acts upstream of or within several processes, including positive regulation of motor neuron apoptotic process; positive regulation of transcription by RNA polymerase II; and regulation of synaptic activity. Located in basement membrane; cell surface; and sarcolemma. Is active in extracellular space and synapse. Is expressed in several structures, including epithelium; lower jaw; musculature; nervous system; and retina. Used to study congenital myasthenic syndrome 8. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 8. Orthologous to human AGRN (agrin). PHENOTYPE: Nullizygous mice display embryonic failure of NMJ formation, inability to breathe or move and perinatal lethality. Homozygotes for an ENU-induced allele show poor hindlimb motor control, myopathy, muscle atrophy, spasms and fiber-type switching, NMJ disaggregation, camptodactyly and premature death.
