CC   -!- FUNCTION: One of the major pre-mRNA-binding proteins. Binds tenaciously
CC       to poly(C) sequences. Likely to play a role in the nuclear metabolism
CC       of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich
CC       sequences. Can also bind poly(C) single-stranded DNA. Plays an
CC       important role in p53/TP53 response to DNA damage, acting at the level
CC       of both transcription activation and repression. When sumoylated, acts
CC       as a transcriptional coactivator of p53/TP53, playing a role in
CC       p21/CDKN1A and 14-3-3 sigma/SFN induction (By similarity). As far as
CC       transcription repression is concerned, acts by interacting with long
CC       intergenic RNA p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53.
CC       This interaction is necessary for the induction of apoptosis, but not
CC       cell cycle arrest. As part of a ribonucleoprotein complex composed at
CC       least of ZNF827, HNRNPL and the circular RNA circZNF827 that nucleates
CC       the complex on chromatin, may negatively regulate the transcription of
CC       genes involved in neuronal differentiation (By similarity).
CC       {ECO:0000250, ECO:0000250|UniProtKB:P61978,
CC       ECO:0000269|PubMed:20673990}.
CC   -!- SUBUNIT: Identified in the spliceosome C complex (By similarity).
CC       Interacts with ANKRD28 and RBM42 (By similarity). Interacts with DDX1
CC       (By similarity). Interacts with MDM2; this interaction leads to
CC       ubiquitination and proteasomal degradation (By similarity). Interacts
CC       with p53/TP53 (By similarity). Interacts with ZIK1 (PubMed:8910362).
CC       Interacts with BRDT (PubMed:22570411). Interacts with IVNS1ABP (By
CC       similarity). Interacts with PPIA/CYPA (By similarity). Part of a
CC       transcription inhibitory ribonucleoprotein complex composed at least of
CC       the circular RNA circZNF827, ZNF827 and HNRNPL (By similarity).
CC       {ECO:0000250|UniProtKB:P61978, ECO:0000250|UniProtKB:P61980,
CC       ECO:0000269|PubMed:22570411, ECO:0000269|PubMed:8910362}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P61978}.
CC       Nucleus, nucleoplasm {ECO:0000250|UniProtKB:P61978}. Cell projection,
CC       podosome {ECO:0000250|UniProtKB:P61978}.

CC       Name=3;
CC         IsoId=P61979-3; Sequence=VSP_012581;
CC   -!- INDUCTION: By DNA damage. This up-regulation is due to protein
CC       stabilization. The constitutive protein levels are controlled by MDM2-
CC       mediated ubiquitination and degradation via the proteasome pathway.
CC       {ECO:0000269|PubMed:16360036}.
CC   -!- PTM: Sumoylated by CBX4. Sumoylation is increased upon DNA damage, such
CC       as that produced by doxorubicin, etoposide, UV light and camptothecin,
CC       due to enhanced CBX4 phosphorylation by HIPK2 under these conditions
CC       (By similarity). {ECO:0000250}.
CC   -!- PTM: Ubiquitinated by MDM2. Doxorubicin treatment does not affect
CC       monoubiquitination, but slightly decreases HNRNPK poly-ubiquitination
CC       (By similarity). {ECO:0000250}.
CC   -!- PTM: O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner.
CC       {ECO:0000250}.
