The information on Functional Families (FunFams) is currently being updated and will be released by the end of March 2012. The pages will include the following features:
  • Multiple alignments for each functional family
  • Representative structure for each functional with known catalytic and interface residues highlighted, along with conserved residues predicted by scorecons
  • Detailed functional information on diversity and conservation within Functional families
  • Multi-domain architectures
In the meantime, please find a summary of information on the FunFams and protein networks within this superfamily on the Gene3D pages:
