Abstract

There is provided a motif-specific, context-independent antibody that specifically binds a recurring, modified motif consisting of (i) at least one sumoylated lysine residue, and (ii) one or more degenerate amino acids bound by a peptide bond to said sumoylated lysine residue, said antibody specifically binding said motif in a plurality of non-homologous peptides or proteins within an organism in which it recurs. Also provided is a motif-specific, context-independent antibody that specifically binds a recurring, modified motif consisting of (i) a C-terminal aspartic acid residue, and (ii) one or more degenerate amino acids bound by a peptide bond to said C-terminal aspartic acid residue, said antibody specifically binding said motif in a plurality of non-homologous peptides or proteins within an organism in which it recurs.
