Enables microtubule plus-end binding activity. Predicted to be involved in several processes, including microtubule cytoskeleton organization; protein localization to microtubule plus-end; and regulation of microtubule polymerization. Predicted to act upstream of or within non-motile cilium assembly; positive regulation of microtubule plus-end binding activity; and protein localization to centrosome. Predicted to be located in several cellular components, including cell projection membrane; focal adhesion; and microtubule cytoskeleton. Predicted to be active in microtubule cytoskeleton. Predicted to colocalize with spindle. Orthologous to human MAPRE1 (microtubule associated protein RP/EB family member 1). [provided by Alliance of Genome Resources, Apr 2022]
