Fmrp phosphorylation

WebThe phosphorylation of FMRP (S500 human, S499 mouse) occurs in the C-terminal region, suggesting that phosphorylation initiates a conformational change in the molecule, allowing it to interact more strongly with AGO in the N-terminus. Likewise, the binding of the N-terminus of MOV10 to FMRP’s KH1 domain most likely changes the conformation of ...
