The Ighmbp2 helicase structure reveals the molecular basis for disease-causing mutations in DMSA1.

abstract：:An important problem in genomics is automatically clustering homologous proteins when only sequence information is available. Most methods for clustering proteins are local, and are based on simply thresholding a measure related to sequence distance. We first show how locality limits the performance of such methods by...
