PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a pleckstrin homology (PH)
	a SH2, a SH3 domains (SRC family, Tec subfamily)
	a BTK-type zinc finger
	a protein kinase domain

HOMOLOGY

Homologene

FAMILY	protein kinase superfamily
	Tyr protein kinase family
	TEC subfamily

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm

basic FUNCTION	involved in T cell activation
	involved in the intracellular signaling mechanisms of cytokine receptors, lymphocyte surface antigens, heterotrimeric G-protein coupled receptors, and integrin molecules
	playing an essential role in phospholipase Cgamma (PLCgamma) activation following antigen receptor stimulation
	regulate activation of the MAPKs in other cell systems, and may be an upstream component of the signaling pathway leading to LPS-induced MAPKs activation in neutrophils (Zemans 2009)
	principal kinase of the Tec family that plays a major role in the responses of neutrophils to monosodium urate monohydrate crystals, which are likely to be involved in the initiation and perpetuation of gout (Popa-Nita 2008)
	may regulate hepatocyte differentiation and is involved in HGF signaling
	promotes the Erk-MAPK signaling pathway and acts downstream of MEK1 kinase but upstream of ERK kinase in HGF signaling
