Protein kinase C eta (PRKCH), also known as PKC-η, is a member of the protein kinase C (PKC) family, which comprises serine/threonine kinases involved in diverse cellular signaling pathways. Encoded by the *PRKCH* gene in humans, this enzyme belongs to the "novel" PKC subfamily (nPKC), characterized by its calcium-independent activation. Unlike classical PKC isoforms, PRKCH requires diacylglycerol (DAG) or phorbol esters for activation but does not depend on calcium ions. Structurally, it contains a regulatory C1 domain for DAG binding and a catalytic kinase domain.
PRKCH plays critical roles in cell proliferation, differentiation, apoptosis, and inflammatory responses. It is highly expressed in epithelial tissues, particularly the skin, where it regulates keratinocyte differentiation and skin barrier formation. In the nervous system, PRKCH influences neuronal development and synaptic plasticity. Dysregulation of PRKCH has been linked to pathological conditions, including cancer, neurodegenerative diseases, and cardiovascular disorders. For instance, overexpression of PRKCH is associated with enhanced cancer cell invasiveness and chemoresistance in certain carcinomas.
Emerging studies highlight its involvement in immune regulation and oxidative stress responses. Genetic variations in *PRKCH*, such as single nucleotide polymorphisms (SNPs), have been correlated with disease susceptibility, including stroke and autoimmune disorders. Additionally, PRKCH interacts with signaling pathways like NF-κB and MAPK, modulating gene expression and cellular adaptation to environmental stressors. Its dual role in both physiological and pathological contexts makes PRKCH a potential therapeutic target, though further research is needed to elucidate its precise mechanisms across different tissues and disease states.
