General annotation (Comments)

Function

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. Ref.13 Ref.22 Ref.27

Subunit structure

Interacts with RBM42 and ZIK1. Interacts with BRDT By similarity. Identified in the spliceosome C complex. Interacts with ANKRD28. Interacts with HCV core protein. Interacts with ASFV p30 protein. Interacts with DDX1. Interacts with MDM2; this interaction leads to ubiquitination and proteasomal degradation. Interacts with p53/TP53. Ref.9 Ref.10 Ref.12 Ref.13 Ref.15 Ref.18

Subcellular location

Cytoplasm. Nucleus › nucleoplasm. Note: Recruited to p53/TP53-responsive promoters, in the presence of functional p53/TP53. In case of ASFV infection, there is a shift in the localization which becomes predominantly nuclear. Ref.1 Ref.13

Induction

By DNA damage, including ionizing radiations and phleomycin treatment or UV irradiation. This induction requires ATM kinase activity (ionizing radiations and phleomycin) or ATR activity (UV irradiation). Up-regulation is due to protein stabilization. Constitutive protein levels are controlled by MDM2-mediated ubiquitination and degradation via the proteasome pathway. Ref.13

Post-translational modification

Arg-296 and Arg-299 are dimethylated, probably to asymmetric dimethylarginine.

Sumoylated by CBX4. Sumoylation is increased upon DNA damage, such as that produced by doxorubicin, etoposide, UV light and camptothecin, due to enhanced CBX4 phosphorylation by HIPK2 under these conditions. Ref.27

Ubiquitinated by MDM2. Doxorubicin treatment does not affect monoubiquitination, but slightly decreases HNRNPK poly-ubiquitination. Ref.13 Ref.27

O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner. Ref.26

Sequence similarities

Contains 3 KH domains.

Mass spectrometry

Isoform 1: Molecular mass is 50976.25 Da from positions 1 - 463. Determined by MALDI. Ref.11

Sequence caution

The sequence BAD92799.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
