| - | ==Overview==
| + | |
| - | In all eukaryotes, CAP-Gly proteins control important cellular processes., The molecular mechanisms underlying the functions of CAP-Gly domains, however, are still poorly understood. Here we use the complex formed, between the CAP-Gly domain of p150(glued) and the C-terminal zinc knuckle, of CLIP170 as a model system to explore the structure-function, relationship of CAP-Gly-mediated protein interactions. We demonstrate that, the conserved GKNDG motif of CAP-Gly domains is responsible for targeting, to the C-terminal EEY/F sequence motifs of CLIP170, EB proteins and, microtubules. The CAP-Gly-EEY/F interaction is essential for the, recruitment of the dynactin complex by CLIP170 and for activation of, CLIP170. Our findings define the molecular basis of CAP-Gly domain, function, including the tubulin detyrosination-tyrosination cycle. They, further establish fundamental roles for the interaction between CAP-Gly, proteins and C-terminal EEY/F sequence motifs in regulating complex and, dynamic cellular processes.
