| Abstract: | A diverse group of proteins known as +TIPs specifically recognize the growing plus ends of microtubules in cells. Two recent papers on one such protein, CLIP-170, provide new insights into the cellular functions of +TIPs as well as the mechanism by which they track microtubule ends. |
