**Background of PLCh1 Recombinant Protein**
Phospholipase C eta 1 (PLCh1), a member of the phospholipase C (PLC) family, plays a critical role in intracellular signaling by hydrolyzing phosphatidylinositol 4.5-bisphosphate (PIP₂) into secondary messengers, inositol 1.4.5-trisphosphate (IP₃) and diacylglycerol (DAG). These molecules regulate calcium release and protein kinase C activation, influencing diverse cellular processes, including proliferation, differentiation, and apoptosis. PLCh1 is distinguished by its unique domain structure, featuring a pleckstrin homology (PH) domain, EF-hand motifs, and catalytic X/Y regions, which enable its interaction with membrane components and signaling partners.
PLCh1 is highly expressed in the brain, particularly in neurons, where it modulates synaptic plasticity, learning, and memory. Its dysfunction has been linked to neurological disorders, such as Alzheimer’s disease, and certain cancers, including glioblastoma. Recombinant PLCh1 protein, produced via expression systems like *E. coli* or mammalian cells, retains enzymatic activity and structural integrity, making it a valuable tool for *in vitro* studies. Researchers utilize it to investigate PLC-mediated signaling pathways, screen for inhibitors or activators, and study mutations associated with disease.
The development of PLCh1 recombinant protein has advanced mechanistic insights into its role in health and disease, offering potential for therapeutic targeting and diagnostic applications in neurology and oncology.
