| Primary Identifier | MGI:1913835 | Organism | mouse, laboratory |
| Chromosome | 4 | NCBI Gene Number | 66585 |
| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Predicted to be involved in RNA splicing, via transesterification reactions. Predicted to be located in cytosol and nuclear speck. Predicted to be part of U4/U6 x U5 tri-snRNP complex and spliceosomal complex. Is expressed in cerebral cortex ventricular layer; liver; lung; metanephros; and submandibular gland primordium. Orthologous to human SNRNP40 (small nuclear ribonucleoprotein U5 subunit 40). PHENOTYPE: Mice homozygous for a knock-out allele show embryonic growth retardation, a small egg cylinder, disorganized extraembryonic tissue, failure to initiate gastrulation, and complete embryonic lethality by E9.5. Mice homozygous for a hypomorphic allelel exhibit reduced body weight, belly spotting, and immunodeficiency. [provided by MGI curators] |
