Domain |
PF01712 Deoxynucleoside kinase |
Function |
Phosphorylates thymidine, deoxycytidine, and deoxyuridine in the mitochondrial matrix. In non-replicating cells, where cytosolic dNTP synthesis is down-regulated, mtDNA synthesis depends solely on TK2 and DGUOK. Widely used as target of antiviral and chemotherapeutic agents. |

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 |

Content |
Relations between abundance of tumor-infiltrating lymphocytes (TILs) and expression, copy number, methylation, or mutation of TK2. The immune-related signatures of 28 TIL types from Charoentong's study, which can be viewed in the download page. For each cancer type, the relative abundance of TILs were inferred by using gene set variation analysis (GSVA) based on gene expression profile. In this tab, users can examine which kinds of TILs might be regulated by the current gene. |
