DCMP: Database of Cancer Mutant Protein Domains

(sponsored by DST-SERB)


Cancers are a large family of diseases that involve abnormal cell growth with the potential to invade or spread to other parts of the body. In 2020 there are predicted to be 20 million new cases and 12 million deaths. Analyses of well-studied cancers, such as colorectal cancer and retinoblastoma, have suggested that only three or less mutations are sufficient for cancer initiation. Group efforts taken from The Cancer Genome Atlas (TCGA), the International Cancer Genome Consortium (ICGC), and Catalogue of Somatic Mutations in Cancer (COSMIC) were made possible to have thousands of cancer genome sequences. In recent years, the genetic landscapes of mutations have been revealed in several cancer types. However, this gene-based approach usually does not consider the position of the mutation within the gene or that which provides the functional context of the position of the mutation. Computational structural studies have explored mutational effects on specific regions of a protein (e.g., the binding site). Recently, we identified significant mutated domains on three cancer diseases: ovarian, breast and prostate cancer. Somatic mutations were mapped to individual protein domains and the local false discovery rate was used to identify significantly mutated domains in each cancer type. This serves as a basis for identifying potentially mutated domains among different cancer types.
