Hipk2 promotes PP1c-mediated Dvl (show DVL2 ELISA Kits) dephosphorylation via its C-terminal domain and is essential Dvl (show DVL2 ELISA Kits) stability.
Our findings indicate that phosphorylation-dependent restriction of SIRT1 (show SIRT1 ELISA Kits) activity by HIPK2 shapes the p53 (show TP53 ELISA Kits) response
The findings highlight a complex regulation of CREB-binding protein (show CREBBP ELISA Kits) activity by HIPK2, which might be relevant for the control of specific sets of target genes involved in cellular proliferation, differentiation and apoptosis.
MDM4 (show MDM4 ELISA Kits)/HIPK2/p53 (show TP53 ELISA Kits) cytoplasmic assembly uncovers coordinated repression of molecules with anti-apoptotic activity during early DNA damage response.
Results indicate that HIPK2 acts as a caretaker gene, whose inactivation increases tumorigenicity and causes chromosomal instability by cytokinesis failure.
HIPK2 expression tends to be decreased along tumor progression and may be involved with the invasive potential, suggesting a possible tumor suppressor role for HIPK2.
c-Abl (show ABL1 ELISA Kits) was required for endogenous HIPK2 accumulation and phosphorylation of p53 (show TP53 ELISA Kits) at Ser46 in response to DNA damage by gamma- and UV radiation.
Lafora disease proteins laforin (show EPM2A ELISA Kits) and malin (show NHLRC1 ELISA Kits) negatively regulate the HIPK2-p53 (show TP53 ELISA Kits) cell death pathway.
HIPK2/HP1gamma (show CBX3 ELISA Kits) pathway may uncover a new functional aspect of HIPK2 as a tumor suppressor.
Analysis of these mutants revealed that HIPK1 (show HIPK1 ELISA Kits), HIPK2 and HIPK3 (show HIPK3 ELISA Kits) but not HIPK4 (show HIPK4 ELISA Kits) are capable of autophosphorylating on other tyrosines
This work describes a novel mechanism of translational suppression by Pdcd4 (show PDCD4 ELISA Kits) and shows for the first time that Hipk2 controls its own synthesis by an auto-regulatory feedback mechanism.
HIPK2 is ubiquitinated upon heat shock.
Phosphorylation of KLF3 (show KLF3 ELISA Kits) and CtBP2 (show CTBP2 ELISA Kits) by HIPK2 strengthens the interaction between these two factors and increases transcriptional repression by KLF3 (show KLF3 ELISA Kits).
Homeodomain-interacting protein kinase 2, a novel autoimmune regulator (show AIRE ELISA Kits) interaction partner, modulates promiscuous gene expression in medullary thymic epithelial cells.
Hipk2 has an essential role in mouse white fat development
data identify Hipk2 as a novel regulator of C/EBPbeta (show CEBPB ELISA Kits) and implicate different protein kinases in the cooperation of p300 (show NOTCH1 ELISA Kits) with C/EBPbeta (show CEBPB ELISA Kits) and C/EBPalpha (show CEBPA ELISA Kits)
Data indicate a critical kinase HIPK2 function in cytokinesis and in the prevention of tetraploidization.
Hipk2 is a haploinsufficient tumor suppressor gene for mouse lymphoma development.
HIPK2 is an important transcriptional cofactor that regulates bone morphogenetic protein signaling in the maintenance of enteric neurons and glia.
HIPK2-mediated phosphorylation of PDX1 (show PDX1 ELISA Kits) at Ser (show SIGLEC1 ELISA Kits)-269 might be a regulatory mechanism connecting signals generated by changes in extracellular glucose concentration to downstream effectors, thereby influencing islet cell differentiation and function.
Expression of Hipk2 in the mouse nucleus accumbens is modulated by a sequence variant (B2 SINE indel) in the 3' UTR (show UTS2R ELISA Kits) of Comt (catechol-O-methyltransferase (show COMT ELISA Kits)).
This gene encodes a conserved serine/threonine kinase that is a member of the homeodomain-interacting protein kinase family. The encoded protein interacts with homeodomain transcription factors and many other transcription factors such as p53, and can function as both a corepressor and a coactivator depending on the transcription factor and its subcellular localization. Multiple transcript variants encoding different isoforms have been found for this gene.
