<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

ABC transporter associated with antigen processing (PubMed:17018292).

In complex with TAP2 mediates unidirectional translocation of peptide antigens from cytosol to endoplasmic reticulum (ER) for loading onto MHC class I (MHCI) molecules (By similarity).

Uses the chemical energy of ATP to export peptides against the concentration gradient (By similarity).

During the transport cycle alternates between 'inward-facing' state with peptide binding site facing the cytosol to 'outward-facing' state with peptide binding site facing the ER lumen. Peptide antigen binding to ATP-loaded TAP1-TAP2 induces a switch to hydrolysis-competent 'outward-facing' conformation ready for peptide loading onto nascent MHCI molecules. Subsequently ATP hydrolysis resets the transporter to the 'inward facing' state for a new cycle (By similarity).

As a component of the peptide loading complex (PLC), acts as a molecular scaffold essential for peptide-MHCI assembly and antigen presentation (By similarity).

The peptide-binding site is shared between the cytoplasmic loops of TAP1 and TAP2.By similarity
The nucleotide-binding domain (NBD) mediates ATP hydrolysis coupled to peptide translocation. Two ATP molecules are accommodated at distinct nucleotide binding sites (NBS) at TAP1-TAP2 dimer interface. Each NBS is formed by Walker A (GxxGxGKST) and Q-loop motifs from NBD of one subunit, while the NBD from the second subunit completes the active site by contributing the C loop motif (LSGGQ). Each ATP molecule is coordinated via the beta- and gamma-phosphates to a Mg2+ ion, which is necessary for ATP hydrolysis.1 Publication

This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

<p>This subsection of the 'Sequence' section reports difference(s) between the protein sequence shown in the UniProtKB entry and other available protein sequences derived from the same gene.<p><a href='/help/sequence_caution' target='_top'>More...</a></p>Sequence cautioni

The sequence CAA40742 differs from that shown. Reason: Erroneous initiation.Curated
