Figure 9. A model for PRMT7-mediated SHANK2 methylation that promotes breast cancer migration through activating endosomal FAK signalling In the absence of PRMT7, SHANK2 cannot interact with dynamin2/talin/FAK/cortactin complex to endosome.
In the presence of PRMT7, R240-methylated SHANK2 disturbs SPN-ANK domain blockade of SHANK2, thereby promoting the co-localization of dynamin2/talin/FAK/cortactin complex on endosome, further activating FAK signalling to promote tumour cells migration.
