MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is part of a complex located in the inner mitochondrial membrane that mediates the transport of transit peptide-containing proteins across the membrane. Multiple transcript variants, one protein-coding and others not protein-coding, have been found for this gene. [provided by RefSeq, Jul 2012]
PHENOTYPE: Mice homozygous for a gene trapped allele die prior to E3.5. Mice heterogygous for this allele exhibit background sensitive premature aging and increased mortality. [provided by MGI curators]
