    Summary
    Enables microtubule binding activity. Predicted to be involved in establishment of mitotic spindle localization; mitotic chromosome condensation; and mitotic cytokinesis. Predicted to act upstream of or within mitotic sister chromatid segregation and positive regulation of mitotic nuclear division. Located in nucleolus. Is active in mitotic spindle. Is expressed in several structures, including genitourinary system; gut; immune system; respiratory system; and skin. Orthologous to human NUSAP1 (nucleolar and spindle associated protein 1).

    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.
