Description

Background
CLSTN1 Protein functions as a postsynaptic adhesion molecule, fostering both excitatory and inhibitory synapse formation by binding to presynaptic neurexins. In the realm of synapse development, CLSTN1 acts as a cell adhesion molecule at the postsynaptic membrane, forming associations with neurexin-alpha at the presynaptic membrane. Beyond its role in synapse formation, CLSTN1 serves as a molecular adapter, participating in axonal anterograde transport by promoting KLC1 association with vesicles. Moreover, it engages in complex formation with APBA2 and APP, stabilizing APP metabolism and enhancing APBA2-mediated suppression of beta-APP40 secretion, contributing to the regulation of intracellular APP maturation. As the intracellular fragment AlcICD, CLSTN1 plays a role in suppressing APBB1-dependent transactivation stimulated by APP C-terminal intracellular fragment (AICD), potentially by competing with AICD for APBB1-binding. These diverse functions underscore the versatile role of CLSTN1 in orchestrating molecular events critical for synapse development and intracellular signaling.
