General description

Tribbles homolog 3 (TRB3) gene is located on the 20p13 human chromosome. TRB3 and its related family members TRB1 and TRB2 show 45% sequence identity. It exhibits resemblance to ′tribbles′, a drosophila protein. TRB family members have a truncated kinase domain that lacks an adenosine 5′-triphosphate binding site (GXGXXG) and contain a variant catalytic core motif.


synthetic peptide corresponding to amino acids 11-29 located near the N-terminus region of human TRB3. The immunizing sequence has limited homology (~50% identity) to mouse and rat TRB3, and has no identity to TRB1 and TRB2 isoforms.


Anti-TRB3 (N-terminal) antibody produced in rabbit has been used in immunoprecipitation and immunoblotting.

Biochem/physiol Actions

Tribbles homolog 3 (TRB3) like tribbles has also been identified as a potential pro-apoptotic protein, and is induced by a variety of cell stress conditions, including hypoxia and nutrient starvation. It was previously identified as a neuronal cell death-inducible protein kinase (NIPK) that is rapidly upregulated during neuronal apoptosis. TRB3 binds to activating transcription factor 4 (ATF4) and inhibits its transcriptional activity. TRB3 has been shown to interact with mitogen-activated protein kinases (MAPK) kinases to regulate activation of MAPK pathways.
