Jun activation domain-binding protein 1 (JAB1, also known as CSN5) is a co-activator of AP-1 that was first identified in its interaction with the activation domain of c-Jun. JAB1 is also a component of the CSN multiprotein complex, which modulates signal transduction, gene transcription, and protein stability. JAB1 interacts with p27, shuttling it from the nucleus to the cytoplasm and decreasing the level of p27 in the cell by increasing its degradation via the ubiquitin-proteasome pathway. An inverse relationship in expression levels of p27 and JAB1 has been reported in various cancer tissues. In a study of 80 cases of epithelial ovarian tumors, JAB1 expression correlated inversely with p27 expression, with JAB1 overexpression significantly associated with poor patient prognosis. Immunohistochemical analysis of a series of 53 invasive breast carcinoma specimens and their adjacent normal breast tissue counterparts also demonstrated an inverse association between JAB1 and p27; patients with no JAB1 expression had the highest survival rate, while patients with high JAB1 levels had the lowest survival rate. JAB1 and p27 are also inversely related in anaplastic large cell lymphoma (ALCL); however, in all 54 patients examined, p27 expression correlated with worse overall survival in both ALK-positive and ALK-negative groups. Applications: Suitable for use in Immunoprecipitation and Western Blot. Other applications have not been tested. Recommended Dilution: Immunoprecipitation: 1-3ug/ml Western Blot: 1-3ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
