Hnrnpk Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
HNRNPK (Heterogeneous Nuclear Ribonucleoprotein K) is an RNA-binding protein involved in multiple aspects of RNA processing, transcription regulation, and signal transduction. It is a recognized ALS risk gene.
HNRNPK is a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family, which plays critical roles in post-transcriptional gene regulation. Located on chromosome 9q21.32, this gene encodes a protein with multiple functional domains including KH domains that facilitate RNA binding. HNRNPK is evolutionarily conserved and expressed ubiquitously across tissues, with particularly high expression in the brain and hematopoietic system.
The protein functions as a modular scaffold that coordinates diverse cellular processes, from RNA splicing and translation to signal transduction and chromatin remodeling. In the context of neurodegenerative disease, HNRNPK has emerged as a significant ALS risk gene, with rare mutations linked to disrupted RNA metabolism and impaired nucleocytoplasmic transport — mechanisms shared with other ALS-associated proteins like TDP-43 and FUS[1].
