Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe Ras family small GTPase Ran is involved in nuclear envelope formation, assembly of the mitotic spindle, and nuclear transport (1,2). TPX2, a target of active Ran (RanGTP), is a microtubule nucleating protein. TPX2 is inactive when bound to nuclear importin-alpha. RanGTP activity disrupts this interaction, relieving inhibition of TPX2 (3). TPX2 binding activates Aurora A kinase and promotes its localization to the mitotic spindle (4,5). DNA damage in mitosis leads to loss of interaction between Aurora A and TPX2 and inactivation of Aurora A kinase (6). TPX2 is highly expressed in pancreatic cancer cells, and knockdown of TPX2 expression in these cells is associated with increased sensitivity to paclitaxel (7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nC20orf1; C20orf2; Differentially expressed in cancerous and non-cancerous lung cells 2; differentially expressed in lung cells; DIL-2; DIL2; FLS353; GD:C20orf1; HCA519; HCTP4; Hepatocellular carcinoma-associated antigen 519; Hepatocellular carcinoma-associated antigen 90; p100; preferentially expressed in colorectal cancer; Protein fls353; REPP86; restricted expression proliferation associated protein 100; Restricted expression proliferation-associated protein 100; Targeting protein for Xklp2; TPX2; TPX2 microtubule nucleation factor; TPX2, microtubule-associated protein homolog; TPX2, microtubule-associated, homolog; TPX2, microtubule-associated, homolog (Xenopus laevis)\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk\nSENSITIVITY: Endogenous\nMW (kDa): 100\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799953658025,"sku":"8559S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-8559s","provider":"Iright","version":"1.0","type":"link"}
