Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific.

Research Backgrounds

P61978_HNRPK_HUMAN

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.

PTMs:

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.

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

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

Subcellular Location:

Cytoplasm. Nucleus>Nucleoplasm. Cell projection>Podosome.
Note: Recruited to p53/TP53-responsive promoters, in the presence of functional p53/TP53 (PubMed:16360036). In case of ASFV infection, there is a shift in the localization which becomes predominantly nuclear (PubMed:18775702).

Subunit Structure:

Interacts with RBM42 and ZIK1 (By similarity). Interacts with BRDT (By similarity). Identified in the spliceosome C complex. Interacts with ANKRD28. Interacts with ASFV p30 protein. Interacts with DDX1. Interacts with MDM2; this interaction leads to ubiquitination and proteasomal degradation. Interacts with p53/TP53. Interacts with IVNS1ABP.

(Microbial infection) Interacts with HCV core protein.
