摘要
We report the expression pattern of a new adenomatous polyposis coli (APC) homolog called E-APC during Drosophila development. E-APC protein is expressed in all embryonic and larval cells we have examined. In the early blastoderm embryo, we see a striking concentration of E-APC in the cortical actin caps. Microtubules are closely associated with these caps. Since human APC has been reported to bind to microtubules, we investigated whether the cortical E-APC co-localizes with tubulin. However, this was not the case, implying that the putative tubulin-binding property of human APC is not well conserved. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
