LRPPRC

Leucine-rich PPR motif-containing protein, mitochondrial is a protein that in humans is encoded by the LRPPRC gene.[1][1][2][3] Transcripts ranging in size from 4.8 to 7.0 kb which result from alternative polyadenylation have been reported for this gene.[3]

Function

Function

This gene encodes a protein that is leucine-rich and is thought to play a role in regulating the interaction of the cytoskeleton with a variety of cellular processes.[4]

Clinical significance

Clinical significance

An integrative genomics strategy led to the discovery that mutations in LRPPRC cause the French-Canadian variant of Leigh syndrome.[5] Furthermore, mutation in the LRPPRC gene causes lowered expression of MT-CO1 (cytochrome c oxidase I) and MT-CO3.[6]
