General description

Membrane-associated RING-CH protein 5 (March5), also known as NKP66, is thought to be a mitochondrial ubiquitin ligase that is localized on the mitochondrial membrane. March5 has a Plant Homeo-Domain (PHD) motif that is essential for E3 ubiquitin ligase action. MARCH 5 is also thought to have four transmembrane domains. March5 has been associated with mitochondrial fission and division. March5 also seems to have a defensive role against mitochondrial dysfunction by interacting with mutant superoxide dismutase 1 (mSOD1) and preventing mSOD1 from causing damage. mSOD1 damage has been linked to the onset and progression of amyotrophic lateral sclerosis.


KLH-conjugated linear peptide corresponding to human March5.

Anti-March5 Antibody is a Rabbit Polyclonal Antibody for detection of March5 also known as Membrane-associated RING finger protein 5 & has been validated in WB, ICC.
Immunocytochemistry Analysis: A representative lot of this antibody was used by an independent laboratory in IC. (Korfali, N., et al. (2010). Mol Cell Proteomics. 9:2571-2585.)


Evaluated by Western Blot in HL-60 cell lysate.

Western Blot Analysis: A 1:2,000 dilution of this antibody detected March5 on 10 µg of HL-60 cell lysate.

Target description

~52 kDa observed

Physical form

Rabbit polyclonal serum containing 0.05% sodium azide.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
