Function

Catalytic component of the m-AAA protease, a protease that plays a key role in proteostasis of inner mitochondrial membrane proteins, and which is essential for axonal and neuron development (PubMed:11549317, PubMed:28396416, PubMed:31097542, PubMed:9635427). SPG7 possesses both ATPase and protease activities: the ATPase activity is required to unfold substrates, threading them into the internal proteolytic cavity for hydrolysis into small peptide fragments (By similarity). The m-AAA protease exerts a dual role in the mitochondrial inner membrane: it mediates the processing of specific regulatory proteins and ensures protein quality control by degrading misfolded polypeptides (By similarity). Mediates protein maturation of the mitochondrial ribosomal subunit MRPL32/bL32m by catalyzing the cleavage of the presequence of MRPL32/bL32m prior to assembly into the mitochondrial ribosome (By similarity). Acts as a regulator of calcium in neurons by mediating degradation of SMDT1/EMRE before its assembly with the uniporter complex, limiting the availability of SMDT1/EMRE for MCU assembly and promoting efficient assembly of gatekeeper subunits with MCU (PubMed:28396416, PubMed:31097542). Also regulates mitochondrial calcium by catalyzing degradation of MCU (PubMed:31097542). Plays a role in the formation and regulation of the mitochondrial permeability transition pore (mPTP) and its proteolytic activity is dispensable for this function (PubMed:26387735).

Activity summary

SPG7 also known as paraplegin is a mitochondrial metalloprotease. It has a molecular mass of approximately 88 kDa. SPG7 is encoded by the SPG7 gene located in humans on chromosome 16. It expresses widely in tissues with a strong presence in the nervous system and muscles. Alternate names for this protein are PGN and spastic paraplegia 7 due to its association with specific neurodegenerative conditions.

Biological function summary

SPG7 functions as a part of the mitochondrial inner membrane m-AAA protease complex. This complex performs essential roles in the maintenance of mitochondrial homeostasis by degrading damaged or misfolded proteins within the mitochondria. The presence of SPG7 is important for proper mitochondrial function. The protein has proteolytic activity which supports mitochondrial respiratory chain complexes' assembly and stability.

Pathways

SPG7 directly involves itself in mitochondrial protein quality control and the broader regulation of mitochondrial function. It interacts closely with ATP-dependent proteases like AFG3L2 playing a significant part in mitochondrial biogenesis pathways. These partnerships are key for maintaining cellular energy balance and ensuring efficient electron transport chain operation.

Associated diseases and disorders

SPG7 mutations connect predominantly to hereditary spastic paraplegia (HSP) and have also been linked to ataxia. These mutations interrupt normal mitochondrial function leading to the degeneration of motor pathways. In HSP SPG7 interacts with proteins such as paraplegin-associated proteins SPG5 and SPG11 contributing to the disorder's pathogenesis. Understanding SPG7’s role in these diseases aids in exploring therapeutic strategies for mitochondrial-related disorders.
