RAD9

Application(s): \nImmunohistochemistry\nImmunoprecipitation\nWestern Blot (1-2ug/ml)\n\n\nRad9 is a cell cycle checkpoint protein: DNA damage leads to extensive phosphorylation of Rad9 [4] which then inhibits progression from G2 in order to preserve cell viability, allowing proper ligation of DNA breaks before the entry of cells into mitosis [1,2]. The human homolog [3] of S. pombe Rad9 is physically proximal to the upstream (DNA damage) signal and associates with two other checkpoint control proteins, Rad1 and HHUS1 [5,6]. Rad9 also interacts with Bcl-2 family proteins Bcl-2 and Bcl-XL, but not with BAX or BAD. Overexpression of Rad9 in mammalian cells leads to apoptosis, where as antisense Rad9 RNA suppresses cell death induced by methyl methanesulphonate [7].\n
