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