CCProf: exploring conformational change profile of proteins

WebbProteins can switch among different conformations in response to their environment to meet their functional roles. In many cases, such conformational changes are the results of binding by other molecules that regulate protein activity. Changes can also be induced by modifying amino acids (e.g., posttranslational modifications on SH2 domains) [ 1 ].
