Regions predicted to be disordered, found to be ordered in experimentally solved complexes of spliceosomal proteins.

(*) Domain names in brackets. (**) ULMs correspond to the ELM motif LIG_ULM_U2AF65_1, defined by the pattern [KR]{1,4}[KR]-x{0,1}-[KR]W-x{0,1}. (***) Non-abundant A-complex protein. (****) The PRP4 region of Prp18 is ordered and its structure in isolation was solved. It is included in the table since the PRP4 region of U4/U6-60K is predicted to be partially disordered.
