背景信息

PEX14 is a critical peroxisomal membrane protein essential for the biogenesis and function of peroxisomes, membrane-bound organelles involved in lipid metabolism, reactive oxygen species detoxification, and bile acid synthesis. As a core component of the peroxisomal protein import machinery, PEX14 interacts with cytosolic receptors like PEX5 and PEX19. facilitating the translocation of matrix proteins into peroxisomes. Its N-terminal α-helical domain forms a docking site for receptor-cargo complexes, while the C-terminal region anchors it to the peroxisomal membrane. Dysregulation of PEX14 is linked to peroxisome biogenesis disorders (e.g., Zellweger spectrum disorders) and has been implicated in viral pathogenesis, cancer, and neurodegenerative diseases.

Recombinant PEX14 proteins are engineered using expression systems (e.g., E. coli, mammalian cells) for structural and functional studies. These proteins retain key domains for receptor binding and membrane association, enabling in vitro reconstitution of protein import complexes. Researchers utilize recombinant PEX14 to investigate peroxisome assembly mechanisms, receptor dynamics, and disease-associated mutations. Its role in host-pathogen interactions (e.g., hepatitis C virus replication) has also spurred interest in antiviral drug development. Structural analyses (X-ray crystallography, cryo-EM) of recombinant PEX14 complexes have revealed molecular details of peroxisomal targeting signal recognition, advancing therapeutic strategies for peroxisomal disorders.
