Characterization of Adenomatous Polyposis Coli Protein Dynamics and Localization at the Centrosome.
The adenomatous polyposis coli (APC) tumor suppressor is a multifunctional regulator of Wnt signaling and acts as a mobile scaffold at different cellular sites. APC was recently found to stimulate microtubule (MT) growth at the interphase centrosome; however, little is known about its dynamics and localization at this site. To address this, we analysed APC dynamics in fixed and live cells by fl...

The other mode of treating these patients are subtotal colectomy with ileorectal anastomosis alongwith regular follow up with proctoscopy for development of cancer in retained rectal mucosa(3,7). Recently, Stevan et al. (8) utilized laproscope for total proctocolectomy as well as ileoanal anostomosis while others performed ileopouch anal anastomosis alongwith total proctocolectomy(9,10). Thus t...
متن کاملRho GTPase Cdc42 Is a Direct Interacting Partner of Adenomatous Polyposis Coli Protein and Can Alter Its Cellular Localization
Adenomatous Polyposis Coli (APC) is a tumor suppressor gene product involved in colon cancer. APC is a large multidomain molecule of 2843 amino acid residues and connects cell-cell adhesion, the F-actin/microtubule cytoskeleton and the nucleus. Here we show that Cdc42 interacts directly with the first three armadillo repeats of APC by yeast two-hybrid screens. We confirm the Cdc42-APC interacti...
متن کاملPhosphorylation near nuclear localization signal regulates nuclear import of adenomatous polyposis coli protein.
Mutation of the adenomatous polyposis coli (APC) gene is an early step in the development of colorectal carcinomas. APC protein is located in both the cytoplasm and the nucleus. The objective of this study was to define the nuclear localization signals (NLSs) in APC protein. APC contains two potential NLSs comprising amino acids 1767-1772 (NLS1(APC)) and 2048-2053 (NLS2(APC)). Both APC NLSs are...
متن کاملAdenomatous Polyposis Coli Associates with the Microtubule-Destabilizing Protein XMCAK
During cell division, the proper formation of a bipolar spindle and its function to segregate chromosomes requires precise coordination of microtubule-stabilizing and destabilizing activities. Globally destabilized, dynamic microtubules radiating from duplicated centrosomes are locally regulated by chromosomes. Proteins at the kinetochore of each sister chromatid mediate a dynamic attachment, a...
