| PAG Description | Integration of pathways that regulate nucleokinesis during neurol migration and a model of LIS1 mediating CLIP-170 interactions with the dynein/dyctin pathway. LIS1 can bind to MT bundles; however, phospho-LIS1 binding to MT bundles is mediated through the distal zinc finger motif of CLIP-170. When the distal zinc finger motif of CLIP-170 is mutated, the phospho-LIS1 isoform can no longer bind to MT bundles. This can also explain why p150/dyctin is not recruited to the MT bundles. CLIP-170 targets the dynein/dyctin complex to the MT, using phopho-LIS1 as an adapter, the motor complex, being in the proximity of the MT, associates with it, the initial static link to the MT provided by CLIP-170 is released by its hyperphosphorylation (step 3); and the retrograde dynein/dyctin-dependent movement of the cargo (endocytic vesicle, kinetochore, etc.) takes place. The RELN pathway is to the right, Cdk5/ p35 in the middle, and the LIS1 pathway is on the left. Doublecortin (DCX) is placed close to the LIS1 pathway based on its interaction with LIS1 and its role in microtubule dymics. |
