TPX2 (human)

TPX2 a microtubule-associated protein required for meiotic and mitotic spindle assembly. Targets a plus end-directed motor (XKLP2) to the minus ends of microtubules in the mitotic spindle. Required for microtubule nucleation around chromosomes in response to the local generation of RanGTP. Binds to and activates Aurora A kinase and targets it to the mitotic spindle. Note: This description may include information from UniProtKB.
Protein type: Cell cycle regulation; Microtubule-binding
Chromosomal Location of Human Ortholog: 20q11.2
Cellular Component: cytosol; microtubule cytoskeleton; nucleoplasm; nucleus; spindle; spindle pole
Molecular Function: ATP binding; GTP binding; protein kinase binding
Biological Process: activation of protein kinase activity; cell proliferation; G2/M transition of mitotic cell cycle; mitosis
Reference #:  Q9ULW0 (UniProtKB)
