Trichoplein keratin filament-binding protein (Tchp)

Tumor suppressor which has the capacity to inhibit cell growth and be pro-apoptotic during cell stress. May act as a 'capping' or 'branching' protein for keratin filaments in the cell periphery.

May regulate K8/K18 filament and desmosome organization mainly at the apical or peripheral areas of simple epithelial cells (By similarity). Is a negative regulator of ciliogenesis (By similarity).
