WebObjective: Upregulation of actin-related protein 2/3 complex subunit 2 (Arp2) is observed in various tumors, but its expression pattern has not been revealed in bladder urothelial carcinoma (BUC). The purpose of this study was to investigate the role of Arp2 expression in the pathological features and the prognosis as well as lymph node ... WebMar 26, 2007 · We determined crystal structures of bovine Arp2/3 complex cocrystallized with various bound adenine nucleotides and cations. Nucleotide binding favors closure of the nucleotide-binding cleft of Arp3, but no large-scale conformational changes in the complex. Thus, ATP binding does not directly activate Arp2/3 complex but is part of a network of ...
