CLSTN1 (CS1, KIAA0911, Calsyntenin-1, Alcadein-alpha, Alzheimer-related Cadherin-like Protein, Non-classical Cadherin XB31alpha, Soluble Alc-alpha, CTF1-alpha, C-terminal Fragment 1-alpha) (Biotin)

Induces KLC1 association with vesicles and functions as a cargo in axonal anterograde transport. Complex formation with APBA2 and APP, stabilizes APP metabolism and enhances APBA2-mediated suppression of beta-APP40 secretion, due to the retardation of intracellular APP maturation. In complex with APBA2 and C99, a C-terminal APP fragment, abolishes C99 interaction with PSEN1 and thus APP C99 cleavage by gamma-secretase, most probably through stabilization of the direct interaction between APBA2 and APP. The intracellular fragment AlcICD suppresses APBB1-dependent transactivation stimulated by APP...
