Paraplegin
Paraplegin is a protein that in humans is encoded by the SPG7 gene.[1][2][3]
This gene encodes a nuclear-encoded mitochondrial metalloprotease protein that is a member of the AAA protein family. Members of this protein family share an ATPase domain and have roles in diverse cellular processes including membrane trafficking, intracellular motility, organelle biogenesis, protein folding, and proteolysis. Two transcript variants encoding distinct isoforms have been identified for this gene. Mutations associated with this gene cause autosomal recessive spastic paraplegia 7.[3]
Interactions
Knockdown of spastic paraplegia 7 by siRNA inhibits the early stages of HIV-1 replication in 293T cells infected with VSV-G pseudotyped HIV-1.[4]
Clinical Significance
It has been shown that an SPG7 variant escapes phosphorylation-regulated processing by AFG3L2 and increases reactive oxygen species generation and is correlated with many clinical phenotypes.[5]
