In this study, we show that the tumor suppressor Tid1 forms a complex with p53 under hypoxic conditions that directs p53 translocation to the mitochondria and the subsequent initiation of the mitochondrial apoptosis pathway.
Recently, we identified htid-1, the human counterpart of the Drosophila tumor suppressor gene lethal(2)tumorous imaginal discs [l(2)tid], as a direct molecular ligand of the adenomatous polyposis coli (APC) tumor suppressor.
Molecular mechanism of hTid-1, the human homolog of Drosophila tumor suppressor l(2)Tid, in the regulation of NF-kappaB activity and suppression of tumor growth.
We report the first case of a tumor-associated mutation at the human TID1 locus, which was identified in the SF767 glioma cell line giving rise to aberrantly high levels of a hTid-1(L) mutant variant.
