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. As far as transcription
CC repression is concerned, acts by interacting with long intergenic RNA
CC p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53. This
CC interaction is necessary for the induction of apoptosis, but not cell
CC cycle arrest (By similarity). As part of a ribonucleoprotein complex
CC composed at least of ZNF827, HNRNPL and the circular RNA circZNF827
CC that nucleates the complex on chromatin, may negatively regulate the
CC transcription of genes involved in neuronal differentiation (By
CC similarity). {ECO:0000250, ECO:0000250|UniProtKB:P61978}.
CC -!- SUBUNIT: Identified in the spliceosome C complex. Interacts with
CC ANKRD28, RBM42 and ZIK1. Interacts with DDX1. Interacts with MDM2; this
CC interaction leads to ubiquitination and proteasomal degradation.
CC Interacts with p53/TP53. Interacts with BRDT (By similarity). Interacts
CC with IVNS1ABP (By similarity). Interacts with PPIA/CYPA (By
CC similarity). Part of a transcription inhibitory ribonucleoprotein
CC complex composed at least of the circular RNA circZNF827, ZNF827 and
CC HNRNPL (By similarity). {ECO:0000250|UniProtKB:P61978,
CC ECO:0000250|UniProtKB:P61979, ECO:0000250|UniProtKB:P61980}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P61978}.
CC Nucleus, nucleoplasm {ECO:0000250|UniProtKB:P61978}. Cell projection,
CC podosome {ECO:0000250|UniProtKB:P61978}.
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}.
