SIRT 2, CT (Sirtuin 2, Silent Mating Type Information Regulation 2, S. cerevisiae Homolog 2)

Silent information regulator 2 (Sir2) family of enzymes has been implicated in many cellular processes that include histone deacetylation, gene silencing, chromosomal stability, and aging. O-acetyl-ADP-ribose causes a delay/block in oocyte maturation and results in a delay/block in embryo cell division in blastomeres. It has been demonstrated that the production of O-acetyl-ADP-ribose is evolutionarily conserved among Sir2-like enzymes from yeast, Drosophila, and human. Also, endogenous yeast Sir2 complex from telomeres was shown to generate O-acetyl-ADP-ribose (1). SIRT2 is a predominantly cytoplasmic protein that colocalizes with microtubules. SIRT2 deacetylates lysine-40 of alpha-tubulin both in vitro and in vivo. Knockdown of SIRT2 via siRNA results in tubulin hyperacetylation. SIRT2 colocalizes and interacts in vivo with HDAC6, another tubulin deacetylase (2). Cytoskeleton-related protein, SIRT2 is down-regulated in gliomas, and data suggests that ectopic expression of SIRT2 in glioma cell lines led to the perturbation of the microtubule network (3).\n\nApplications:\nSuitable for use in Flow Cytometry, ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000 \nImmunocytochemistry: 1:100-1:250 \nFlow Cytometry: 1:30 \nImmunoprecipitation: 1:50 \nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees 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. \n\nManufactured incorporating RabMAb(R) technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
