Protein BEX1 (Bex1)

Signaling adapter molecule involved in p75NTR/NGFR signaling. Plays a role in cell cycle development and neuronal differentiation.

Inhibits neuronal differentiation in response to nerve growth factor (NGF). May act as a link between the cell cycle and neurotrophic factor signaling, possibly by functioning as an upstream modulator of receptor signaling, coordinating biological responses to external signals with inner cellular states (By similarity).
