Subcellular Location Endoplasmic reticulum membrane; Multi-pass membrane protein. Note=The transmembrane segments seem to form a pore in the membrane.
Domain PF00664 ABC transporter transmembrane region
PF00005 ABC transporter
Function

Involved in the transport of antigens from the cytoplasm to the endoplasmic reticulum for association with MHC class I molecules. Also acts as a molecular scaffold for the final stage of MHC class I folding, namely the binding of peptide. Nascent MHC class I molecules associate with TAP via tapasin. Inhibited by the covalent attachment of herpes simplex virus ICP47 protein, which blocks the peptide-binding site of TAP. Inhibited by human cytomegalovirus US6 glycoprotein, which binds to the lumenal side of the TAP complex and inhibits peptide translocation by specifically blocking ATP-binding to TAP1 and prevents the conformational rearrangement of TAP induced by peptide binding. Inhibited by human adenovirus E3-19K glycoprotein, which binds the TAP complex and acts as a tapasin inhibitor, preventing MHC class I/TAP association.

16517708Head and Neck Squamous Cell CarcinomaPromote immunity (T cell function)First, lack of recognition of SCCHN cells by CTL is associated with marked down-regulation of the IFN-gamma-inducible APM components low-m.w. protein 2, TAP1, TAP2, and tapasin.
28783722MelanomaPromote immunity (T cell function); essential for immunotherapyOn the basis of our initial optimization of the 2CT-CRISPR assay, we expected that genes directly associated with MHC class I antigen processing and presentation would be enriched in our screens, and found that HLA-A, B2M, TAP1, TAP2, and TAPBP were among the most highly-enriched genes in our screen.Significant resistance was detected in the cells transduced with B2M sgRNAs (72 ± 5%) and with TAP2 sgRNAs (13 ± 2%) against the cytolytic activity of ESO T cells. Loss of expression of these 19 genes within tumours could diminish or extinguish the presentation of tumour antigens (including HLA-A, HLA-F, B2M, TAP1 and TAP2); T cell co- stimulation (ICAM1, CLECL1, LILRA1 and LILRA3); or cytokine production and signalling (JAK2 and STAT1) in the tumour microenvironment that drive infiltration and activation of T cells, and thus serve as a principal mechanism in immune evasion.
27496866Head and Neck CarcinomaPromote immunity (T cell function); essential for immunotherapyCD137 agonist mAb urelumab enhanced cetuximab-activated NK-cell survival, DC maturation, and tumor antigen cross-presentation. Urelumab boosted DC maturation markers, CD86 and HLA DR, and antigen-processing machinery (APM) components TAP1/2, leading to increased tumor antigen cross-presentation. These results suggest a beneficial effect of combination immunotherapy using cetuximab and CD137 agonist in HNC.
18519766Ovarian CancinomaPromote immunity (infiltration)The majority of APM component expression examined was significantly associated with both intratumoral and peritumoral T-cell infiltration (P < 0.05). The expression of APM components and the presence of intratumoral T-cell infiltrates were significantly associated with improved survival (all P < or = 0.01);

Content High-throughput screening data (e.g. CRISPR-Cas9, shRNA and RNAi) for T cell-mediated killing. Genetic screen techniques can identify mechanisms of tumor cell resistance (e.g., PTPN2) and sensitivity (e.g., APLNR) to killing by cytotoxic T cells, the central effectors of anti-tumor immunity. After comprehensively searching, eight groups of screening data sets were collected in the current database. In this tab, users can check whether their selected genes cause resistance or increase sensitivity to T cell-mediated killing in various data sets.

Content Transcriptomic and genomic profiling of pre-treated tumor biopsies from responders and non-responders to immunotherapy. These data were used to identify signatures and mechanisms of response to checkpoint blockade (e.g., anti-PDL1 and anti-PD1). One example is that mutations in the gene PBRM1 benefit clinical survival of patients with clear cell renal cell carcinoma. After comprehensively searching, we collected 5 and 6 of transcriptomic and genomic data sets, respectively. In this tab, users can check whether their selected genes have significant difference of expression or mutation between responders and non-responders in various data sets.
