General description

The 70 kDa peroxisomal membrane protein (PMP70) is a major component of peroxisomal membranes. The peroxisome is a multifunctional single-membrane organelle associated with eukaryotic cells. PMP70 belongs to the ATP binding cassette (ABC) transporter superfamily.

Immunogen

synthetic peptide corresponding to amino acid residues 644-659 of rat PMP70 with N-terminal added cysteine, conjugated to KLH. The corresponding sequence is identical in mouse and differs by one amino acid in human.

Application

Anti-PMP70 antibody produced in rabbit has been used in:
  • immunocytochemistry
  • immunostaining
  • immunofluorescence
  • western blotting
  • immunoprecipitation

Biochem/physiol Actions

PMP70 participates in the metabolic transport of long and very long fatty acids into peroxisomes. PMP70 interacts and forms a stable complex with the adrenoleukodystrophy protein(ALDP), and also with several other peroxisomal proteins. ATP binding/hydrolysis by PMP70 and ALDL and their phosphorylation are involved in the regulation of fatty acid transport into peroxisomes. Mutations in the PMP70 (PXMP1) gene may cause a subset of Zellweger syndrome, an autosomal recessive disorder and is characterized by defects in import mechanism for peroxisomal matrix enzymes.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Organelle Isolation

The isolation of subcellular fractions by centrifugation is a commonly used technique and is widely applicable across multiple cell and tissue types. Because organelles differ in their size, shape, and density, centrifugation can be easily employed to separate and purify organelle fractions from gently homogenized samples.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
