Anti-AIP1/WD repeat-containing protein 1, clone 13F10 Antibody clone 13F10, from rat

Actin-interacting protein 1 (AIP1), also known as WD repeat-containing protein 1 (Wdr1), is a key player in cytoskeletal rearrangements and actin mobilization, and thus plays a role in many cellular situations from movement to cytokinesis. AIP1 interacts with Cofilin as well, and Cofilin regulates actin filament dynamics by stimulating actin filament disassembly and also plays a critical role in cytokinesis and chemotactic migration. Knockdown of AIP1 in HeLa cells increased the percentage of multinucleate cells and the mechanics of cytokinesis were altered with an excessive buildup of actin filaments at telophase. The results could be relieved by overexpression of Cofilin pointing to AIP1's critical role in Cofilin-mediated actin filament disassembly. Furthermore, AIP1 inhibition caused abnormal cell migration in response to cytokine stimulation leading to a non-directional migration phenotype thus indicating that AIP1 plays an important directional role in response to stimuli as well. Finally AIP1, as one might expect, plays a critical role in development of cells and tissues, especially in epithelial morphogenesis for instance.
