-	[[https://www.uniprot.org/uniprot/HNRPK_HUMAN HNRPK_HUMAN]] One of the major pre-mRNA-binding proteins. Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA. Plays an important role in p53/TP53 response to DNA damage, acting at the level of both transcription activation and repression. When sumoylated, acts as a transcriptional coactivator of p53/TP53, playing a role in p21/CDKN1A and 14-3-3 sigma/SFN induction (By similarity). As far as transcription repression is concerned, acts by interacting with long intergenic RNA p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53. This interaction is necessary for the induction of apoptosis, but not cell cycle arrest.<ref>PMID:16360036</ref> <ref>PMID:20673990</ref> <ref>PMID:22825850</ref>	+	[https://www.uniprot.org/uniprot/HNRPK_HUMAN HNRPK_HUMAN] One of the major pre-mRNA-binding proteins.

-	== Publication Abstract from PubMed ==
-	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.

		+	[[http://www.uniprot.org/uniprot/HNRPK_HUMAN HNRPK_HUMAN]] One of the major pre-mRNA-binding proteins. Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA. Plays an important role in p53/TP53 response to DNA damage, acting at the level of both transcription activation and repression. When sumoylated, acts as a transcriptional coactivator of p53/TP53, playing a role in p21/CDKN1A and 14-3-3 sigma/SFN induction (By similarity). As far as transcription repression is concerned, acts by interacting with long intergenic RNA p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53. This interaction is necessary for the induction of apoptosis, but not cell cycle arrest.<ref>PMID:16360036</ref> <ref>PMID:20673990</ref> <ref>PMID:22825850</ref>

		+	== Publication Abstract from PubMed ==
		+	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.
