Function

Broad substrate specificity ATP-dependent transporter of the ATP-binding cassette (ABC) family that catalyzes the transport of long-chain fatty acids (LCFA)-CoA, dicarboxylic acids-CoA, long-branched-chain fatty acids-CoA and bile acids from the cytosol to the peroxisome lumen for beta-oxydation. Has fatty acyl-CoA thioesterase and ATPase activities (By similarity). Probably hydrolyzes fatty acyl-CoAs into free fatty acids prior to their ATP-dependent transport into peroxisomes (By similarity). Thus, play a role in regulation of LCFAs and energy metabolism namely, in the degradation and biosynthesis of fatty acids by beta-oxidation (PubMed:10207018).

Supplementary info

Activity summary

PMP70 also known as ABCD3 is a peroxisomal membrane protein with a molecular weight of approximately 70 kDa. It belongs to the ATP-binding cassette (ABC) transporter family and localizes on the peroxisomal membrane predominantly expressed in liver kidney and testes. PMP70 plays an important mechanical role in the transportation of very long-chain fatty acids (VLCFAs) across the peroxisomal membrane.

Biological function summary

This protein operates as part of a heterodimeric complex with its related transporter protein ALDP (ABCD1). PMP70 facilitates the import of VLCFAs into peroxisomes which are then subjected to β-oxidation. By doing this PMP70 contributes significantly to the metabolism of lipids maintaining internal cellular homeostasis.

Pathways

PMP70 integrates into the peroxisomal β-oxidation pathway alongside other proteins such as ALDP and ACSVL1. It ensures the proper flux of VLCFAs into peroxisomes which is essential for their breakdown and energy production. The protein also interacts with metabolic pathways linked to lipid biosynthesis and degradation illustrating its multifaceted role in cellular lipid management.

Associated diseases and disorders

PMP70's dysfunction relates to X-linked adrenoleukodystrophy (X-ALD) a severe genetic disorder affecting the nervous system and adrenal glands. Mutations in PMP70 and related proteins particularly ALDP disrupt VLCFA degradation leading to toxic accumulation. This highlights the clinical significance of PMP70 and its potential as a therapeutic target in metabolic and neurodegenerative diseases.

Immunofluorescence analysis was performed on A-431 cells (untransfected, panel a,d), transfected with non-specific scrambled siRNA (panels b,e) and transfected with PMP70 specific siRNA (panel c,f). Cells were fixed, permeabilized, and labelled with PMP70 Rabbit Polyclonal Antibody (5 μg/ml), followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 (1:2000). Nuclei (blue) were stained using ProLong™ Diamond Antifade Mountant with DAPI, and Rhodamine Phalloidin (1:300) was used for cytoskeletal F-actin (red) staining. Reduction of specific signal was observed upon siRNA mediated knockdown (panel c,f) confirming specificity of the antibody to PMP70 (green). The images were captured at 60X magnification.
