Description
TRIB3 or tribbles homolog 3 protein encode one of three members of the Tribbles family that share a Trb domain, which is homologous to protein serine-threonine kinases, but lacks the active site lysine and probably lacks a catalytic function. TRIB3 is a negative regulator of NF-kappaB and can also sensitize cells to TNF- and TRAIL-induced apoptosis. TRIB3 can negatively regulate the cell survival serine-threonine kinase AKT1. TRIB3 modulation by H. pylori and/or its products may be an important mechanism of H. pylori-associated pathogenesis. TRIB3 is a p65-interacting negative regulator of NF-kappa-B-dependent transcription. TRIB3 is highly expressed in pancreas, peripheral blood leukocytes, and bone marrow
