Applications | In H4IIE hepatoma cells, D4476 specifically inhibited the phosphorylation of endogenous forkhead box transcription factor O1a (FOXO1a) on Ser322 and Ser325 within its MPD, without affecting the phosphorylation of other sites. It was also found that although the treatment of in HCT116 cells with D4476 led to a partial p53-dependent growth arrest, the induction of p53-independent apoptosis by D4476 suggested a critical role for the MDM2-CK1 complex in maintaining E2F-1 anti-apoptotic signaling. |
| 产品描述 | D4476 is a relatively specific and cell-permeant inhibitor of CK1 and ALK5 with respective IC50 values of 0.3 and 0.5 μM at 0.1 mM ATP in vitro.[1] CK1 (casein kinase 1) phosphorylates serine residues that are located close to another phosphoserine in multisite phosphorylation domains (MPDs). D4476 may be an ATP-competitive inhibitor of CK1. It weakly inhibits SAPK2a/p38 and does not inhibit PKB or SGK. In H4IIE cells, the site-specific phosphorylation (Ser322 and Ser325) of FOXO1a was inhibited at 50 and 125 μM, which reduced the initial rate of nuclear exclusion[1]. In Hela cells, the phosphorylation(Ser185) of RhoB caused by CK1 was inhibited by D4476 at 50 μM then the RhoB-dependent actin fiber formation was subsequently activated[2]. D4476 treatment has been observed to result in a partial p53-dependent growth arrest in HCT116 cells.[3] References: |
