Function

Serine/threonine-protein kinase involved in transcription regulation, p53/TP53-mediated cellular apoptosis and regulation of the cell cycle. Acts as a corepressor of several transcription factors, including SMAD1 and POU4F1/Brn3a and probably NK homeodomain transcription factors. Phosphorylates PDX1, ATF1, PML, p53/TP53, CREB1, CTBP1, CBX4, RUNX1, EP300, CTNNB1, HMGA1, ZBTB4 and DAZAP2. Inhibits cell growth and promotes apoptosis through the activation of p53/TP53 both at the transcription level and at the protein level (by phosphorylation and indirect acetylation). The phosphorylation of p53/TP53 may be mediated by a p53/TP53-HIPK2-AXIN1 complex. Involved in the response to hypoxia by acting as a transcriptional co-suppressor of HIF1A. Mediates transcriptional activation of TP73. In response to TGFB, cooperates with DAXX to activate JNK. Negative regulator through phosphorylation and subsequent proteasomal degradation of CTNNB1 and the antiapoptotic factor CTBP1. In the Wnt/beta-catenin signaling pathway acts as an intermediate kinase between MAP3K7/TAK1 and NLK to promote the proteasomal degradation of MYB. Phosphorylates CBX4 upon DNA damage and promotes its E3 SUMO-protein ligase activity. Activates CREB1 and ATF1 transcription factors by phosphorylation in response to genotoxic stress. In response to DNA damage, stabilizes PML by phosphorylation. PML, HIPK2 and FBXO3 may act synergically to activate p53/TP53-dependent transactivation. Promotes angiogenesis, and is involved in erythroid differentiation, especially during fetal liver erythropoiesis. Phosphorylation of RUNX1 and EP300 stimulates EP300 transcription regulation activity. Triggers ZBTB4 protein degradation in response to DNA damage. In response to DNA damage, phosphorylates DAZAP2 which localizes DAZAP2 to the nucleus, reduces interaction of DAZAP2 with HIPK2 and prevents DAZAP2-dependent ubiquitination of HIPK2 by E3 ubiquitin-protein ligase SIAH1 and subsequent proteasomal degradation (PubMed:33591310). Modulates HMGA1 DNA-binding affinity. In response to high glucose, triggers phosphorylation-mediated subnuclear localization shifting of PDX1. Involved in the regulation of eye size, lens formation and retinal lamination during late embryogenesis.

Activity summary

HIPK2 also known as Homeodomain-interacting protein kinase 2 is a serine/threonine kinase with a molecular mass of approximately 118 kDa. This protein plays a mechanical role in modulating transcriptional regulation and apoptosis. It interacts with homeodomain transcription factors influencing the activity of various gene promoters. Within cells HIPK2 is expressed widely in several tissues including the heart brain and liver highlighting its diverse functional involvement across different biological systems.

Biological function summary

The wide-ranging actions of HIPK2 make it essential for cell growth apoptosis and stress response. HIPK2 associates with various transcription factors and other-binding partners forming dynamic complexes that mediate its functions. By phosphorylating target proteins it regulates p53 and promotes p53-mediated apoptosis making it an important part of stress response networks. Additionally HIPK2 is implicated in the regulation of Wnt signaling pathways which are important for cell proliferation and differentiation processes.

Pathways

HIPK2 plays an integrative role in apoptotic and Wnt signaling pathways. It serves as a facilitator of the DNA damage response primarily through the modulation of p53 activity. It also contributes to the Wnt signaling pathway by phosphorylating beta-catenin and enhancing its degradation therefore regulating cellular proliferation. The interactions of HIPK2 with proteins like p53 and beta-catenin illustrate its significant involvement in controlling cell fate and maintaining cellular homeostasis.

Associated diseases and disorders

HIPK2 is linked to various cancers and neurodegenerative diseases due to its role in apoptosis and cell cycle regulation. Disruption in HIPK2 activity leads to impaired apoptosis and contributes to tumorigenesis particularly in cancers like breast and colorectal cancer. In neurodegenerative disorders such as Alzheimer's disease abnormal HIPK2 activity is associated with altered cellular signaling. The relationship with key proteins like p53 further explains how deviations in HIPK2 function can lead to disease states making it a valuable target for therapeutic interventions.
