Abstract

This paper presents the development of a protein interaction database. The developed system is characterized as follows. First, the proposed system not only maintains interaction data collected by an experiment, but also the genomic information of the protein data. Secondly, the system can extract details on interacting proteins through the developed wrappers. Thirdly, the system is based on wrapper-based system in order to extract the biologically meaningful data from various web sources and integrate them into a relational database. The system inherits a layered-modular architecture by introducing a wrapper-mediator approach in order to solve the syntactic and semantic heterogeneity among multiple data sources. Currently the system has wrapped the relevant data for about 40% of about 11,500 proteins on average from various accessible sources. A wrapper-mediator approach makes a protein interaction data comprehensive and useful with support of data interoperability and integration. The developing database will be useful for mining further knowledge and analysis of human life in proteomics studies.

이 논문은 단백질 상호작용 데이터베이스 개발에 관해 기술한다. 개발된 시스템의 특징으로서는 첫째, 생물학자들의 직접적인 실험을 통해 얻어진 단백질 상호작용 및 유전인자 데이터를 제공한다. 둘째, 생물학적으로 관련 있는 다양한 형식의 데이터를 wrapper를 통해 광범위하게 분포된 웹사이트들로부터 추출한다. 셋째, 다양한 웹 데이터들 간의 어휘적, 의미적 이질성을 완화하기 위해 wrapper-mediator에 의한 계층적 모듈 구조를 이용하여 추출된 데이터는 통합 과정을 거친 후, 데이터베이스 저장 및 검색을 가능하게 하였다. 현재까지, 주어진 약 11,500 단백질들에 대해, 생물적으로 의미 있는 데이터를 약 40% 정도 데이터베이스 화 했다. 본 개발된 시스템은 프로티오믹스 연구에서 데이터 분석에 유용할 것으로 기대된다.
