Vaccinia-related kinase 1 messenger RNA (VRK1 mRNA) (VRK1 mRNA)

Vaccinia-related kinase 1 (VRK1) mRNA is the transcript encoding a serine/threonine kinase that is essential for cell cycle progression, DNA repair, and nuclear envelope assembly (UniProt P49759). The protein product of this mRNA phosphorylates several critical substrates, including p53, BAF, and histones, thereby maintaining genomic stability and regulating chromatin condensation (PubMed: 16118237). VRK1 is frequently overexpressed in a wide range of human cancers, including glioblastoma, breast cancer, and lung cancer, where it correlates with high proliferation rates and poor patient prognosis (PubMed: 30104618). Consequently, targeting VRK1 mRNA via RNA interference (RNAi) or antisense oligonucleotides (ASOs) has emerged as a promising therapeutic strategy to deplete the protein and inhibit tumor growth. Furthermore, VRK1 has been identified as a synthetic lethal target in tumors with low expression of its paralog, VRK2, providing a potential therapeutic window for precision medicine (PubMed: 28380356). Beyond oncology, mutations in the VRK1 gene are associated with rare motor neuron diseases and neurodegenerative disorders, underscoring its vital role in cellular homeostasis (PubMed: 21549344).
