AFG3L2 (AFG3 Like Matrix AAA Peptidase Subunit 2) is a Protein Coding gene. Diseases associated with AFG3L2 include Spinocerebellar Ataxia 28 and Ataxia, Spastic, 5, Autosomal Recessive. GO annotations related to this gene include metalloendopeptidase activity and unfolded protein binding.This gene encodes a protein localized in mitochondria and closely related to paraplegin. The paraplegin gene is responsible for an autosomal recessive form of hereditary spastic paraplegia. This gene is a candidate gene for other hereditary spastic paraplegias or neurodegenerative disorders.
