Summary: The protein encoded by this gene catalyzes the conversion of isopentenyl diphosphate to dimethylallyl diphosphate, which is a precursor for the synthesis of cholesterol and other isoprenoids. This gene, which is a product of an ancestral gene duplication event, encodes a protein that may be involved in the aggregation of alpha-synuclein in the cerebral cortex of patients with Lewy body disease. In addition, segmental copy number gains in this locus have been associated with sporadic amyotrophic lateral sclerosis. [provided by RefSeq, Jul 2016]

What's a GeneRIF?

The present findings suggest that IDI1 and IDI2 may be associated with the production of cholesterol metabolites in neurons, leading to alpha-synuclein aggregation during the process of Lewy body formation.
Title: Isopentenyl diphosphate isomerase, a cholesterol synthesizing enzyme, is localized in Lewy bodies.
Within the 40-kb region on 10p15.3 subtelomere, which harbours two genes encoding isopentenyl diphosphate isomerase 1 (IDI1) and IDI2, there was found a segmental copy-number gain in a large proportion of sporadic amyotrophic lateral sclerosis patients.

Title: A scan of chromosome 10 identifies a novel locus showing strong association with late-onset Alzheimer disease.
Enzyme kinetic analysis; both isozymes IDI1 and IDI2 are localized to the peroxisome by a PTS1-dependent pathway; data suggest that IDI2 is regulated independently from IDI1, by a mechanism that may involve PPARalpha
Title: IDI2, a second isopentenyl diphosphate isomerase in mammals.
IDI2 is expressed at high levels only in skeletal muscle, where it may be involved in the specialized production of isoprenyl diphosphates for the posttranslational modification of proteins.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
