In Western blot, ab180611 was shown to bind specifically to TAP2. A band was observed at 75 kDa in wild-type HeLa cell lysates with no signal observed at this size in Tap2 knockout cell line ab265426 (knockout cell lysate ab258712). To generate this image, wild-type and Tap2 knockout HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

TAP2 also known as Transporter 2 ATP Binding Cassette Subfamily B Member has a mass of approximately 76 kDa. It functions as a part of the peptide-loading complex where it plays a mechanical role in transporting antigen peptides into the endoplasmic reticulum. TAP2 is expressed primarily in antigen-presenting cells such as B cells dendritic cells and macrophages. It is an integral membrane protein located in the membrane of the endoplasmic reticulum.
Biological function summary

The TAP2 protein operates as an important component of the immune system by facilitating the processing and presentation of antigens. It partners with TAP1 and forms a heterodimer complex essential for the transportation of peptides that are 8-16 amino acids long. This action is fundamental for the proper presentation of antigens on major histocompatibility complex (MHC) class I molecules which are pivotal in the recognition of infected or abnormal cells by cytotoxic T lymphocytes.

Pathways

The TAP2 protein plays a significant role in the antigen processing and presentation pathways. It directly impacts the MHC class I pathway by aiding in the selection and transport of peptides that bind to MHC class I molecules. TAP2 functions alongside related proteins such as TAP1 and tapasin which help facilitate the loading of these peptides onto MHC class I molecules in the endoplasmic reticulum preparing them for cell surface presentation.

Mutations or deficiencies in the TAP2 gene are associated with bare lymphocyte syndrome type 1 (BLS1) a rare immunodeficiency disorder. This syndrome relates to a shortage of antigen presentation on MHC class I molecules leading to increased susceptibility to viral infections. TAP2 along with its partner protein TAP1 is critical in maintaining regular immune surveillance and any disruption in their function can result in profound immunological consequences including impaired cytotoxic T cell responses.

Target data

ABC transporter associated with antigen processing. In complex with TAP1 mediates unidirectional translocation of peptide antigens from cytosol to endoplasmic reticulum (ER) for loading onto MHC class I (MHCI) molecules (PubMed : 25377891, PubMed : 25656091). Uses the chemical energy of ATP to export peptides against the concentration gradient (PubMed : 25377891). 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 (PubMed : 11274390, PubMed : 25377891, PubMed : 25656091). Typically transports intracellular peptide antigens of 8 to 13 amino acids that arise from cytosolic proteolysis via IFNG-induced immunoproteasome. Binds peptides with free N- and C-termini, the first three and the C-terminal residues being critical. Preferentially selects peptides having a highly hydrophobic residue at position 3 and hydrophobic or charged residues at the C-terminal anchor. Proline at position 2 has the most destabilizing effect (PubMed : 11274390, PubMed : 7500034, PubMed : 9256420). As a component of the peptide loading complex (PLC), acts as a molecular scaffold essential for peptide-MHCI assembly and antigen presentation (PubMed : 1538751, PubMed : 25377891, PubMed : 26611325).
