인간 ATP 결합카세트 수퍼페미리 단백질 분류를 위한 서브페미리 특이적인 모티프 프로화일링

The ATP binding cassette (ABC) transporter superfamily is ubiquitous in all three domains of life. The cellular and molecular functions of ABC transporters are diverse and essential to all living organisms. In human, mutations associated with ABC transporters are known to cause many genetic diseases. Although the members of ABC transporter superfamily share common sequential feature, the subfamily recognition is not a trivial task because of its domain complexity. The functional annotation begins with subfamily recognition. Here, we showed that a motif profiling provides simple and intuitive approach to recognize the subfamily level. Along with relation to the structural feature, the motif profiling approach will be a guide to annotate and understand molecular functions of subfamilies with a big superfamily
