MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that interacts with the DNA polymerase delta p50 subunit, as well as with proliferating cell nuclear antigen. The encoded protein maybe play a role in the ability of the replication fork to bypass DNA lesions. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]
PHENOTYPE: Mice homozygous for a gene trap allele exhibit preweaning lethality and decreased body size. Mice heterozygous for this allele exhibit abnormal induced vasoconstriction and vasodilation with abnormal aorta elastic tissue morphology. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at position 817 of the Poldip2 transcript in exon 9 of 11 total exons.  Multiple transcripts of the Poldip2 gene are displayed on Ensembl. The mutated nucleotide causes an isoleucine to methionine substitution at amino acid 267 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Poldip2gene encodes a 368 amino acid nuclear protein that interacts with PCNA and POLD2 (polymerase delta 2) and contains a protein-interacting ApaG domain at amino acids 235-360 (Uniprot Q91VA6). 
The I267M change is predicted to be possibly damaging by the PolyPhen program.
