From: A method to assess compositional bias in biological sequences and its application to prion-like glutamine/asparagine-rich domains in eukaryotic proteomes

1 (Q+N)-rich domains according to a Q, N or Q+N bias* 172 22 853 315 213 194
2 (1) plus filter for charged and hydrophobic residues 96 14 473 216 125 69
3 (2) plus requirement for a subsidiary bias for G, Y or S 31 7 86 80 35 21
  1. *The total number of (Q+N)-rich domains. These are all LPSs that have a Q or N bias with Pbias < 1 × 10-13 or a {QN} bias with Pbias < 1.8 × 10-14. †A filter is used so that only LPSs that have a subsidiary bias against {DERK} with a Pbias < 6.5 × 10-3 and against {VILM} with a Pbias < 2 × 10-2 are considered. A filter is used so that only LPSs that have a subsidiary bias for one of the residues G, Y or S with a Pbias < 5 × 10-4 are considered.
