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.

2 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.

2 GO annotations of biological process

Name Definition
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.
regulation of MAP kinase activity Any process that modulates the frequency, rate or extent of MAP kinase activity.
