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