Transmembrane proteins from ABC proteins family (ATP-binding cassette proteins) with ATPase activity, ensuring the efflux of anionic lipophils molecules out of cells.
P-glycoprotein (permeability glycoprotein, abbreviated as P-gp or Pgp) is a well-characterized ABC-transporter of the MDR/TAP subfamily also called ABCB1 (for ATP-binding cassette sub-family B member 1, MDR1, and PGY1).
Topoisomerases (type I or type II) are enzymes that unwind and wind DNA, in order for DNA to control the synthesis of proteins, and in order for DNA to reproduce.
Topoisomérase II alpha,
Topoisomérase II beta,
Topoisomérase III alpha
Major vault protein, also known as MVP, is a cancer resistance-related protein containing Vaults, that are multi-subunit structures involved in nucleo-cytoplasmic transport.
