Anti-Lonp antibodies enable researchers to detect and measure the Lonp antigen in biological samples. This target is a reported synonym of the LONP1 gene, which encodes lon peptidase 1, mitochondrial. This protein is known to function in pathways of aging and the response to oxidative stress, among other biological roles. The human version of Lonp has a canonical amino acid length of 959 residues and a protein mass of 106.5 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Lonp is a member of the Peptidase S16 protein family.
