DESCRIPTION

Also known as HNRPK_HUMAN, HNRNPK, HNRPK. 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. Interacts with RBM42 and ZIK1 (By similarity). Interacts with BRDT (By similarity). Identified in the spliceosome C complex (PubMed:11991638). Interacts with ANKRD28 (PubMed:16564677). Interacts with ASFV p30 protein (PubMed:18775702). Interacts with DDX1 (PubMed:12183465). Interacts with MDM2; this interaction leads to ubiquitination and proteasomal degradation (PubMed:16360036). Interacts with p53/TP53 (PubMed:16360036). Interacts with IVNS1ABP (PubMed:23825951). Interacts with PPIA/CYPA (PubMed:25678563).
