MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors that play a key role in the maintenance of cholesterol balance in the body. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. This gene has been shown to be imprinted, with preferential expression from the maternal allele only in placenta. Transcript variants encoding different isoforms have been identified.

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 2470 of the Osbpl5 transcript in exon 19 of 22 total exons. Four transcripts of the Osbpl5 gene are displayed on Ensembl. The mutated nucleotide causes an isoleucine to phenylalanine substitution at amino acid 744 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Osbpl5 gene encodes an 898 amino acid protein that belongs to the OSBP (oxysterol binding protein) family (NP_077251). On Uniprot (Q9ER64), the protein is 874 amino acids long and is missing 24 amino acids from the N-terminus. The protein contains a lipid-binding pleckstrin homology (PH) domain at amino acids 126-243 when using the Uniprot record. 
 
The I744F change is predicted to be possibly damaging by the PolyPhen program.
