Rabbit HNRNPK Polyclonal Antibody | anti-HNRNPK antibody
HNRNPK Antibody
Phosphate buffered saline, pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
IHC: 1:50-1:200
IF/ICC: 1:100-1:500
Immunofluorescence (IF)
(MBS9607219 staining NIH-3T3 cells by IF/ICC. The sample were fixed with PFA and permeabilized in 0.1% Triton X-100, then blocked in 10% serum for 45 minutes at 25 degree C. The primary antibody was diluted at 1/200 and incubated with the sample for 1 hour at 37 degree C. An Alexa Fluor 594 conjugated goat anti-rabbit IgG (H+L) antibody, diluted at 1/600, was used as secondary antibody.)
Immunohistochemistry (IHC)
(MBS9607219 at 1/100 staining Rat heart tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary.)
Western Blot (WB)

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.
Subunit Structure: 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).
Post-translational Modifications: 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.
NCBI and Uniprot Product Information
Predicted: 51 kDa
NCBI Description
This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene is located in the nucleoplasm and has three repeats of KH domains that binds to RNAs. It is distinct among other hnRNP proteins in its binding preference; it binds tenaciously to poly(C). This protein is also thought to have a role during cell cycle progession. Several alternatively spliced transcript variants have been described for this gene, however, not all of them are fully characterized. [provided by RefSeq, Jul 2008]

Product Notes
The HNRNPK hnrnpk (Catalog #AAA9607219) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The HNRNPK Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's HNRNPK can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemisty (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), ELISA (EIA). WB: 1:500-1:2000 IHC: 1:50-1:200 IF/ICC: 1:100-1:500. Researchers should empirically determine the suitability of the HNRNPK hnrnpk for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "HNRNPK, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
