Anti-Prostate Apoptosis Response Protein 4 (Par4 Induced by Effectors of Apoptosis, PAWR, PRKC Apopt

The tumor suppressor WT1 represses and activates transcription. The loss and/or imbalance of the dual transcriptional activity of WT1 may contribute to Wilms' tumor. Par-4 (for prostate apoptosis response) is a WT1-interacting protein that also functions as a transcriptional repressor. Par-4 contains a putative leucine zipper domain and is specifically upregulated during apoptosis of prostate cells. Cellular Localization: Cytoplasm. Nucleus. Note: Mainly cytoplasmic in absence of apoptosis signal and in normal cells. Nuclear in most cancer cell lines. Nuclear entry seems to be essential but not sufficient for apoptosis. Nuclear localization includes nucleoplasm and PML nuclear bodies. , Applications: , Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
