The Transporter Associated With Antigen Processing (TAP): Structural Integrity, Expression, Function, and Its Clinical Relevance

Abstract excerpt

BACKGROUND: The transporter associated with antigen processing (TAP), a member of the family of ABC transporters, plays a crucial role in the processing and presentation of the major histocompatibility complex (MHC) class I restricted antigens. TAP transports peptides from the cytosol into the endoplasmic reticulum, thereby selecting peptides matching in length and sequence to respective MHC class I molecules....
