Cancers are a large family of diseases that involve abnormal cell growth to invade or spread to other parts of the body. Analyses of well-studied cancers, such as colorectal cancer and retinoblastoma, have suggested that only three or fewer mutations are sufficient for cancer initiation. Group efforts are 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 mutation position within the gene or provide the functional context of that mutation. This study determines the significantly mutated domains (SMDs) among different cancers from the human proteome. Somatic mutations were mapped to the protein domains, and the SMDs were selected using statistical methods.

The database facilitates users to explore mutated protein domains for different cancer types, and it consists of the following three primary menus: domain genomic positions, SMDs and mutated domains.

1. Domain Genomic Positions: The first menu display the chromosome positions for any given protein domain with references to the ensemble.
2. Significantly Mutated Domains: The second menu illustrates the top 10 SMDs with references to the Pfam database.
3. Mutated Domains: The last menu provides a complete list of mutated protein domains for any cancer type.
