DAG1 and Lissencephaly: Central to cobblestone lissencephaly hypotheses is post-translational regulation of dystroglycan (coded by DAG1, dystrophin-associated glycoprotein 1), a glycoprotein present in RG basal processes, that acts as an anchor point with the ECM (Booler et al., 2016), being also important for BM structure (Henry and Campbell, 1998).
