  Function in Host
One of the major pre-mRNA-binding proteins. Binds tenaciouslyto poly (C) sequences. Likely to play a role in the nuclear metabolismof hnRNAs, particularly for pre-mRNAs that contain cytidine-richsequences. Can also bind poly (C) single-stranded DNA. Plays animportant role in p53/TP53 response to DNA damage, acting at the levelof both transcription activation and repression. When sumoylated, actsas a transcriptional coactivator of p53/TP53, playing a role inp21/CDKN1A and 14-3-3 sigma/SFN induction. As far astranscription repression is concerned, acts by interacting with longintergenic RNA p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53. This interaction is necessary for the induction of apoptosis, but notcell cycle arrest. As part of a ribonucleoprotein complex composed atleast of ZNF827, HNRNPL and the circular RNA circZNF827 that nucleatesthe complex on chromatin, may negatively regulate the transcription ofgenes involved in neuronal differentiation.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [5]
Infected TissueLung Infection Time24 h
Infected CellA549 Cells (Adenocarcinomic Human alveolar basal epithelial cells) Cellosaurus IDCVCL_H249 
Method DescriptionTo detect the role of host protein HNRNPK in viral infection, HNRNPK protein knockout A549 Cells were infected with SARS-COV-2 for 24 h , and the effects on infection was detected through qRT-PCR.
ResultsIt is reported that Knockdown of HNRNPK leads to the decreased the percent of infected cells 50% compared with control group.
