Hipk2 relocalization
WebbHere we describe a mechanism through which HMGA1 inhibits p53-mediated apoptosis by counteracting the p53 proapoptotic activator homeodomain-interacting protein kinase 2 (HIPK2). We found that HMGA1 overexpression promoted HIPK2 relocalization in the … WebbHomeodomain-interacting protein kinase 2 (HIPK2) is a tumor suppressor mediating growth suppression and apoptosis upon genotoxic stress through phosphorylation of p53 at Ser46. Here we show that Src phosphorylates HIPK2 and changes its subcellular localization. Using mass spectrometry we identified 9 Src-mediated Tyr-phosphorylation …
