The 70-kDa peroxisomal membrane protein is a member of the Mdr (P-glycoprotein)-related ATP-binding protein superfamily.

The 70-kDa peroxisomal membrane protein (PMP70) is one of the major integral membrane proteins of rat liver peroxisomes. cDNA clones for PMP70 were isolated and sequenced. The predicted amino acid sequence (659 amino acid residues) revealed that the carboxyl-terminal region of PMP70 has strong se…
