HGNC id	30809

FLASH GENE DNA RNA EXPRESSION PROTEIN DISORDER ANIMAL & CELL MODELS

PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	three distinct domains, a proline-rich N-terminus
	a serine/threonine kinase homology domain, kinase domain is essential for its function
	variant catalytic loop sequences compared to conventional kinases that are necessary for its activity
	a C-terminal COP1 binding domain

HOMOLOGY

interspecies	homolog to murine Trib2 (98.3pc)
	homolog to rattus Trib2 (98.0pc)

Homologene

FAMILY	protein kinase superfamily
	CAMK Ser/Thr protein kinase family
	Tribbles subfamily

CATEGORY

regulatory , antigen

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytoskeleton

basic FUNCTION	interacting with MAPK kinases and regulating activation of map kinases
	uveitis-associated candidate autoantigen
	potent novel regulator of monocyte biology, controlling the activation of these cells
	regulate gene expression by modulation of protein kinase signaling pathways
	regulate activation of a number of intracellular signalling pathways with roles extending from mitosis and cell activation to apoptosis and modulation of gene expression
	repressor of FOXO transcription factors, that contributes to the malignant phenotype of melanoma cells
	can bind both COP1 and CEBPA, leading to degradation of CEBPA
	potential driver of lung tumorigenesis through a mechanism that involves downregulation of CEBPA

INTERACTION

DNA

RNA

small molecule

protein	binding partner and a negative regulator of selected MAPKs
	can bind both RFWD2 and CEBPA, leading to degradation of CEBPA
	TRIB2 associated-BTRC, RFWD2 and SMURF1 reduced TCF4/CTNNB1 expression, and these effects could be enhanced by TRIB2
