FERMT1 encodes kindlin-1, a 77 kDa protein that plays a crucial role in cell-matrix adhesion and integrin signaling 1. The protein localizes at focal adhesions and is essential for linking the actin cytoskeleton to the extracellular matrix via integrin-mediated contacts 2. FERMT1 is primarily expressed in basal keratinocytes where it regulates cell adhesion, proliferation, and migration 2. Mechanistically, FERMT1 functions as a mechanotransduction mediator, sensing biomechanical signals through ITGB1 and activating downstream pathways including PI3K/Akt and Wnt signaling 34. Loss-of-function mutations in FERMT1 cause Kindler syndrome, a rare autosomal recessive genodermatosis characterized by skin blistering, photosensitivity, progressive poikiloderma, and increased skin cancer risk 56. Unlike other epidermolysis bullosa forms, Kindler syndrome involves impaired actin-extracellular matrix interactions rather than keratin-matrix linkage defects 2. Clinically, FERMT1 overexpression is associated with enhanced epithelial-mesenchymal transition and cancer progression in various malignancies, suggesting potential therapeutic targeting opportunities 73. The protein's diverse roles span from maintaining skin integrity to regulating cancer cell stemness and chemoresistance 4.
