General annotation (Comments)

Function	Plays a crucial role in B-cell ontogeny. Transiently phosphorylates GTF2I on tyrosine residues in response to B-cell receptor cross-linking. Required for the formation of functional ARID3A DNA-binding complexes. Ref.6 Ref.7 Ref.9 Ref.10
Catalytic activity	ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Enzyme regulation	Inhibited by IBTK By similarity. Activated by phosphorylation.
Subunit structure	Binds GTF2I through the PH domain. Interacts with SH3BP5 via the SH3 domain. Interacts with IBTK via its PH domain By similarity. Interacts with GTF2I and ARID3A.
Subcellular location	Cytoplasm. Membrane; Peripheral membrane protein. Nucleus. Ref.9
Domain	The PH domain mediates the binding to inositol polyphosphate and phosphoinositides. Ref.8
Post-translational modification	Autophosphorylated on Tyr-223 and Tyr-551. Phosphorylation of Tyr-223 may create a docking site for a SH2 containing protein. Ref.7 Ref.5 Ref.11
Involvement in disease	Defects in Btk are the cause of murine X-linked immunodeficiency (XID). Ref.9 Ref.12
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. Contains 1 SH3 domain.
