| + | The heterogeneous nuclear ribonucleoprotein (hnRNP) K is implicated in multiple functions in the regulation of gene expression and acts as a hub at the intersection of signaling pathways and processes involving nucleic acids. Central to its function is its ability to bind both ssDNA and ssRNA via its KH (hnRNP K homology) domains. We determined crystal structures of hnRNP K KH3 domain complexed with 15-mer and 6-mer (CTC(4)) ssDNAs at 2.4 and 1.8 A resolution, respectively, and show that the KH3 domain binds specifically to both TCCC and CCCC sequences. In parallel, we used NMR to compare the binding affinity and mode of interaction of the KH3 domain with several ssRNA ligands and CTC(4) ssDNA. Based on a structure alignment of the KH3-CTC(4) complex with known structures of other KH domains in complex with ssRNA, we discuss recognition of tetranucleotide sequences by KH domains. | ||
