Genes affected

CLPP (HGNC:2084): (caseinolytic mitochondrial matrix peptidase proteolytic subunit) The protein encoded by this gene belongs to the peptidase family S14 and hydrolyzes proteins into small peptides in the presence of ATP and magnesium. The protein is transported into mitochondrial matrix and is associated with the inner mitochondrial membrane. [provided by RefSeq, Jul 2008]
