abcIs3 [pie-1p::ebp-2::GFP + unc-119(+)]. Superficially wild-type. Maternal expression of EBP-2::GFP microtubule end-binding protein. In early embryos, EBP-2 encodes an EB1-like protein (end-binding) that locates to the growing tips of microtubules (not detected on depolymerizing microtubules). A strong fluorescent signal localizes to the centrosome due to high concentration of polymerizing microtubule ends. References: Gusnowski EM, Srayko M. J Cell Biol. 2011 Aug 8;194(3):377-86.
