Background Information

OMA1 (Overlapping with the m-AAA protease 1 homolog) is also named as MPRP1 (Metalloprotease-related protein 1) and belongs to the peptidase M48 family. It is a zinc metalloprotease that spans the inner mitochondrial membrane with a number of predicted membrane spanning domains and the 60 kDa form of OMA1 rapidly accumulated concomitantly with the cleavage of all OPA1 variants, the 40 kDa form of OMA1 may be the mature form (M-OMA1), and the 35 kDa is a cleaved form (S-OMA1), with the 60 kDa form being the active enzyme (PMID:20334834, 30518622). This antibody is speicific to OMA1.
