Subcellular Location	Endoplasmic reticulum membrane Single-pass type II membrane protein
Domain	PF11838 ERAP1-like C-terminal domain PF01433 Peptidase family M1
Function	Aminopeptidase that plays a central role in peptide trimming, a step required for the generation of most HLA class I-binding peptides. Peptide trimming is essential to customize longer precursor peptides to fit them to the correct length required for presentation on MHC class I molecules. Preferentially hydrolyzes the basic residues Arg and Lys.

21252114	Lymphoma	Promote immunity	The endoplasmic reticulum aminopeptidase ERAAP is involved in the final trimming of peptides for presentation by MHC class I (MHC-I) molecules. Herein, we show that ERAAP silencing results in MHC-I peptide-loading defects eliciting rejection of the murine T-cell lymphoma RMA in syngeneic mice. Because a large fraction of human tumors express high levels of the homologous ERAP1 and/or ERAP2, the present findings highlight a convenient, novel target for cancer immunotherapy.

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. > Expression difference between responders and non-responders > Mutation difference between responders and non-responders
