Protein attributes

Sequence length	675 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Activity is required for interleukin 6 (IL-6) induced differentiation. May play a role in the growth and differentiation of hematopoietic cells. May be involved in signal transduction in endocardial and arterial endothelial cells. Ref.2
Catalytic activity	ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Subunit structure	Interacts with RUFY1 and RUFY2. Ref.8
Subcellular location	Cytoplasm Probable.
Tissue specificity	Preferentially expressed in epithelial and endothelial cells.
Induction	Activated by IL-6 through phosphatidylinositol 3-kinase (PI3-kinase) pathway. It is likely that activation occurs through binding of phosphoinositides to the PH domain. Ref.2
Domain	SH2 domain mediates interaction with RUFY1.
Sequence similarities	Belongs to the protein kinase superfamily. Tyr protein kinase family. TEC subfamily. Contains 1 Btk-type zinc finger. Contains 1 PH domain. Contains 1 protein kinase domain. Contains 1 SH2 domain.
