8.A.233. The Scotin (Shisa-5) Family Scotin (Shisa-5) can induce apoptosis in a caspase-dependent manner and plays a role in p53/TP53-dependent apoptosis. Scotin is a novel p53-inducible proapoptotic protein located in the ER and the nuclear membrane (Bourdon et al. 2002). proposed that SCOTIN impedes the ER-to-Golgi transport through its ability to form biomolecular condensates at the ER membrane (Kim et al. 2023).
