PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	one ITAM motif (immunoreceptor tyrosine-based activation motif)
	five conserved putative tyrosine phosphorylation sites (Pan 2007)
	a structural domain that mediates its interaction with the PDZ-RhoGEF protein
	C-terminal tyrosine residue

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,organelle,mitochondria
	intracellular,nucleus
text	expressed in the cytoplasm of germinal center lymphocytes
	constitutively localised in the plasma membrane but is excluded from lipid rafts

basic FUNCTION	may have an important role in the diagnosis of specific lymphomas, and, potentially in the identification of subtypes associated with different prognoses
	involved in negative regulation of lymphocyte migration, thus constraining lymphocytes to the germinal center
	may be an adaptor protein in GC B cells that transduces signals from GC B-cell membrane to the cytosol via its association with GRB2
	germinal center (GC)-specific gene that negatively regulates lymphocyte motility and whose expression predicts improved survival of patients with diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma (cHL)

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	interacting with IL6 (IL6 induces the phosphorylation of the C-terminal tyrosine residue of GCET2 via the Lyn kinase, and promotes its relocalization from the cytoplasm to podosome-like structures)
	associate with GRB2 through the third tyrosine following phosphorylation
