Family: Short-chain cytokines

Lineage:

  1. Root: scop
  2. Class: All alpha proteins [46456]
  3. Fold: 4-helical cytokines [47265]
    core: 4 helices; bundle, closed; left-handed twist; 2 crossover connections
  4. Superfamily: 4-helical cytokines [47266]
    there are two different topoisomers of this fold with different entanglements of the two crossover connections
