LY6H (Lymphocyte Antigen 6 Family Member H) is a cell surface protein belonging to the LY6/uPAR superfamily, characterized by a conserved LU domain with 8-10 cysteine residues forming disulfide bonds. It is anchored to the plasma membrane via a glycosylphosphatidylinositol (GPI) moiety and plays roles in cell signaling, adhesion, and immune regulation. Initially identified in immune cells, LY6H is also expressed in the nervous system, particularly in cholinergic neurons, suggesting involvement in neurodevelopment and synaptic function.
Research links LY6H to neurological and oncological contexts. It interacts with nicotinic acetylcholine receptors (nAChRs), modulating neurotransmission and neuroprotection. Dysregulation of LY6H has been associated with Alzheimer’s disease, where reduced expression may impair cholinergic signaling. In gliomas, LY6H overexpression correlates with tumor progression, possibly through EGFR pathway activation or immune evasion mechanisms.
Recombinant LY6H protein is engineered in vitro using expression systems like E. coli or mammalian cells (e.g., HEK293), followed by purification via affinity chromatography. Quality assessments include SDS-PAGE, Western blotting, and mass spectrometry to confirm purity and structural integrity. This recombinant form facilitates functional studies, antibody development, and drug screening. For example, it aids in mapping protein-protein interactions, screening small-molecule inhibitors, or generating diagnostic tools for LY6H-related pathologies.
Current research focuses on LY6H’s dual role as a neuroprotective agent and a potential oncogenic marker, highlighting its therapeutic relevance. However, its precise mechanisms remain partially unresolved, necessitating further exploration of its signaling networks and tissue-specific functions.
