HIPK2 Proteins

Protein Information

The HIPK2 gene encodes a member of the homeodomain-interacting protein kinase family, specifically a serine/threonine nuclear protein kinase. HIPK2 plays versatile roles in cellular processes, including transcription regulation, cell proliferation, differentiation, and apoptosis. It interacts with various transcription factors and proteins, contributing significantly to the modulation of gene expression. Notably, HIPK2 is involved in the activation of the tumor suppressor protein p53, with p53-dependent pro-apoptotic activity, positioning HIPK2 as a potential tumor suppressor gene. Recent studies highlight its downregulation in multiple tumor types and its emerging role in cancer biology and therapy. Its expression is subject to quality control mechanisms, including autophosphorylation at serine and threonine sites. Structurally, the crystal structure of HIPK2 reveals unique conformational attributes that contribute to its functionality in different signaling pathways. HIPK2's influence extends to physiological processes, such as fibrosis and central nervous system regulation, indicating its broad biological significance and potential therapeutic applications.
