Abstract: | Assembly of antigen-presenting complexes between class I MHC molecules and peptide requires formation of a complex between the 'ABC' peptide transporter, TAP, and newly synthesized class I molecules. Recent studies have provided new insights into the role of ATP in peptide binding, transport and release. |
