Genetic manipulation studies have also shown the involvement of PS1 in brain development, but PS2 remains largely unexplored. In order to understand how PS1 and 2 mediate developmental functions, we have investigated the interaction of PS1 and 2 with proteins of mouse cerebral cortex during development. Co-immunoprecipitation (Co-IP) combined with MALDI-MS/MS analysis revealed 12 interacting partners of PS1 and 11 partners of PS2. The interacting proteins were different for PS1 and 2, and involved in cell division, glycolysis, cell adhesion and protein trafficking. Densitometric analysis of protein bands visualized after SDS-PAGE separation of Co-IP proteins revealed variation in their amount and degree of interaction during different developmental stages of mice. Further, immunoblot based validation of PS1 interacting protein Notch-1 showed maximum interaction at embryonic day (E) 12.5, decline at E18.5, upregulation from postnatal day 0 (P0) to P20 and thereafter reduction at P45 and 20 weeks. In-silico analysis of PS and its interacting proteins indicated conformation based interaction through common type of secondary structures having alpha helical, extended beta strand and random coil, and CK2, PKC phosphorylation and myristoylation motifs. Taken together, our study showed that PS1 and PS2 interact to varying extent with different proteins of mouse cerebral cortex and suggests their interaction based on specific conformation and involvement in diverse functions essential for the brain development."xsd:string |
