The amino acid sequence of human CNBP. The seven Cys-Cys-His-Cys (CCHC) type zinc knuckle domains (C-Φ-X-C-G-X3-H-X4-C, where Φis an aromatic amino acid and X is a variable amino acid) in the human CNBP protein are underlined. The RG sequence between zinc finger ZF1 and ZF2 is indicated with shading. The peptide sequence identified by MS/MS is boxed.
