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. As part of a ribonucleoprotein complex composed at least of ZNF827, HNRNPL and the circular RNA circZNF827 that nucleates the complex on chromatin, may negatively regulate the transcription of genes involved in neuronal differentiation (PubMed:33174841).

Heterogeneous nuclear ribonucleoprotein K (hnRNP K) is a multifunctional protein that plays a critical role in RNA metabolism including RNA splicing translation and transcription. Alternate names for hnRNP K include synkaryon-associated protein and hnRNP KurB. It has a molecular mass of approximately 51 kDa and is ubiquitously expressed in the nucleus and cytoplasm of eukaryotic cells. This protein features three KH (K homology) domains that enable it to interact with nucleic acids and other proteins.
HnRNP K serves as a transcriptional regulator and participates in the assembly of ribonucleoprotein complexes. As part of the ribonucleoprotein complex it interacts with both RNA and DNA influencing various gene expression pathways. It also modulates the activity of several transcription factors including c-Myc and has been implicated in cell proliferation and differentiation. This protein's versatile functions make it an important component in various cellular processes.
HnRNP K plays an important role in signal transduction and the p53 pathway. In the p53 pathway hnRNP K acts as a coactivator enhancing the transcriptional activity of the tumor suppressor p53 and influencing cell cycle regulation and apoptosis. Additionally hnRNP K interacts with several proteins including the c-Myc oncogene to regulate gene expression associated with growth and cell cycle progression.
HnRNP K has been linked to cancer and neurological disorders. Its interaction with c-Myc makes it relevant in various cancers where c-Myc is dysregulated contributing to unchecked cell proliferation. Furthermore alterations in hnRNP K expression or function have been associated with neurodegenerative disorders where it might interact with proteins like TDP-43 or FUS affecting neuronal function and survival.

Overlay histogram showing HeLa cells stained with ab23644 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab23644, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (Goat Anti-Mouse IgG H&L (DyLight® 488) preadsorbed ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (Mouse IgG1, Kappa Monoclonal [B11/6] - Isotype Control ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
IHC image of hnRNP K staining in a section of formalin-fixed paraffin-embedded normal human colon* performed on a Leica BOND™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab23644, 1ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
