Summary: Predicted to enable several functions, including magnesium ion binding activity; microtubule nucleator activity; and protein homodimerization activity. Involved in microtubule polymerization; nervous system development; and positive regulation of myelination. Located in cytoplasm and nucleus. Colocalizes with microtubule. Is expressed in several structures, including central nervous system; genitourinary system; gut; hemolymphoid system gland; and nasal cavity epithelium. Orthologous to human TPPP (tubulin polymerization promoting protein). [provided by Alliance of Genome Resources, Dec 2024]

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.
