Aberrant localization of p44/WDR77 in the cytoplasm is associated with prostate tumorigenesis. Here, we describe studies that used the mouse prostate and human prostate cancer cells as model systems to investigate signals that control subcellular localization of p44/WDR77. We observed distinct subcellular location of p44/WDR77 during prostate development. p44/WDR77 localizes in the cytoplasm at the early stage of prostate development, when prostate epithelial cells are rapidly proliferating, and in the nucleus in adult prostate, when epithelial cells are fully differentiated. Subcellular localization assays designed to span the entire open-reading frame of p44/WDR77 protein revealed the presence of two nuclear exclusion signal (NES) and three nuclear localization signal (NLS) sequences in the p44/WDR77 protein. Site-directed mutagenesis of critical residues within an NLS led to loss of nuclear localization and transcriptional activity of p44/WDR77, suggesting that nuclear localization of p44/WDR77 is essential for its function as a transcriptional cofactor for AR. Three identified NLS were not functional in AR-positive prostate cancer (LNCaP and 22RV1) cells, which led to localization of p44/WDR77 in cytoplasm. The function of NLS in LNCaP cells could be restored by factor(s) from Cos 7 or PC3 cells. Mass spectrometric (MALDI-TOF/TOF) analysis identified proteins associated with an NLS and an NES in prostate cancer cells. These results provide a basis for understanding subcellular transport of p44/WDR77 during prostate development and tumorigenesis."xsd:string |
