Summary: Enables importin-alpha family protein binding activity and protein kinase binding activity. Involved in mitotic spindle assembly and regulation of mitotic spindle organization. Located in axon hillock and spindle. Is expressed in cerebral cortex ventricular layer; large intestine; nephrogenic zone; and small intestine. Orthologous to human TPX2 (TPX2 microtubule nucleation factor). [provided by Alliance of Genome Resources, Dec 2024]

Downregulation of TPX2 impairs the antitumor activity of CD8+ T cells in hepatocellular carcinoma.
Title: Downregulation of TPX2 impairs the antitumor activity of CD8+ T cells in hepatocellular carcinoma.
Depleting TPX2 decreases microtubule formation frequency specifically at the tip and the base of the neurite, and these correlate precisely with the regions where active GTP-bound Ran proteins are enriched.
Title: Ran-dependent TPX2 activation promotes acentrosomal microtubule nucleation in neurons.
Bcl2l10, Tpx2, and Aurka co-localized on the meiotic spindles, and Bcl2l10 was present in the same complex with Tpx2.
Title: Bcl2l10, a new Tpx2 binding partner, is a master regulator of Aurora kinase A in mouse oocytes.
Study demonstrates that the Golgi resident protein GM130 activates the spindle assembly factor TPX2 to nucleate microtubules around the Golgi and further captures them to couple mitotic membranes to the spindle.
Title: GM130 Regulates Golgi-Derived Spindle Assembly by Activating TPX2 and Capturing Microtubules.
The findings indicated that Tpx2 is essential for maintaining genomic stability through its role in spindle regulation.
Title: Tpx2 controls spindle integrity, genome stability, and tumor development.
Tpx2 redistributes from the nucleus to the apical process, and promotes nuclear migration during G2-phase by altering microtubule organization.

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.
