MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] INTS1 is a subunit of the Integrator complex, which associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A; MIM 180660) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 180680) and U2 (RNU2; MIM 180690) (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Homozygous mutation of this gene results in embryonic lethality at the blastocyst stage. [provided by MGI curators]

Nature of Mutation
DNA sequencing using the SOLiD technique identified an A to G transition at position 1821 of the Ints1 transcript, in exon 10 of 47 total exons. The mutated nucleotide causes a glutamic acid to glycine substitution at amino acid 538 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
Ints1 encodes the 2195 amino acid integrator complex subunit 1 (Ints1) protein. The integrator complex is involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. The integrator complex is associated with the C-terminal domain (CTD) of the largest RNA polymerase II subunit (POLR2A), and is recruited to the U1 and U2 snRNA genes. Two isoforms are displayed on Uniprot (Uniprot Q6P4S8). Homozygous knockout of the Ints1 gene in mice results in embryonic lethality at the blastocyst stage.
 
The E538G mutation is predicted to be possibly damaging by the PolyPhen program.
