Descriptions
TRIB1 controls the levels of C/EBPs involved in the differentiation of myeloid cells and adipocytes by recruiting the proteins to COP1 ubiquitin ligase. TRIB1 recognizes a conserved stretch within a transactivation domain of C/EBP proteins, and suggests a model by which TRIB1 acts as a dynamic adapter for recruiting C/EBPs to COP1. TRIB1 contains a pseudokinase domain and this pseudokinase interacts with the COP1-binding motif and prevents the recruitment of COP1 ubiquitin ligase.

3 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytoskeleton | A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
5 GO annotations of molecular function
| Name | Definition |
|---|---|
| mitogen-activated protein kinase kinase binding | Binding to a mitogen-activated protein kinase kinase, a protein that can phosphorylate a MAP kinase. |
| protein kinase inhibitor activity | Binds to and stops, prevents or reduces the activity of a protein kinase. |
| RNA polymerase II-specific DNA-binding transcription factor binding | Binding to a sequence-specific DNA binding RNA polymerase II transcription factor, any of the factors that interact selectively and non-covalently with a specific DNA sequence in order to modulate transcription. |
| ubiquitin protein ligase binding | Binding to a ubiquitin protein ligase enzyme, any of the E3 proteins. |
| ubiquitin-protein transferase regulator activity | Binds to and modulates the activity of a ubiquitin-protein transferase, an enzyme that catalyzes the covalent attachment of ubiquitin to lysine in a substrate protein. |
6 GO annotations of biological process
| Name | Definition |
|---|---|
| negative regulation of DNA-binding transcription factor activity | Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of a transcription factor, any factor involved in the initiation or regulation of transcription. |

| negative regulation of interleukin-10 production | Any process that stops, prevents, or reduces the frequency, rate, or extent of interleukin-10 production. |
| positive regulation of proteasomal ubiquitin-dependent protein catabolic process | Any process that activates or increases the frequency, rate or extent of the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome. |
| positive regulation of ubiquitin-protein transferase activity | Any process that activates, maintains or increases the rate of ubiquitin transferase activity. |
| regulation of MAP kinase activity | Any process that modulates the frequency, rate or extent of MAP kinase activity. |
