LIN7C (Lin-7 Homolog C, Crumbs Cell Polarity Complex Component): LIN7C is a protein that represents the role of the LIN7 family in establishing and maintaining cell polarity. It is crucial for proper cell function and tissue organisation, particularly in neural and epithelial cells. Mutations or dysregulation of LIN7C can disrupt cell polarity and signalling, potentially contributing to developmental abnormalities or disease.
