Summary: Enables microtubule plus-end binding activity. Involved in microtubule bundle formation and microtubule polymerization. Acts upstream of or within non-motile cilium assembly; protein localization to centrosome; and protein localization to microtubule. Located in Golgi apparatus; cell projection membrane; and microtubule cytoskeleton. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Orthologous to human MAPRE1 (microtubule associated protein RP/EB family member 1). [provided by Alliance of Genome Resources, Jun 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
