General annotation (Comments)

Function

Implicated in the control of cell growth. Plays a role in the regulation of intracellular calcium levels. Required in brain development and mature brain function with important roles in the regulation of axon growth, axon guidance, and neurite extension. Role in CNTN1-mediated signaling. Ref.2

Catalytic activity

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Cofactor

Manganese.

Enzyme regulation

Inhibited by phosphorylation of Tyr-528 by leukocyte common antigen and activated by dephosphorylation of this site By similarity.

Subunit structure

Associates through its SH3 domain, to the p85 subunit of phosphatidylinositol 3-kinase.

Tissue specificity

Thymus and spleen. Ref.1

Sequence similarities

Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily.

Contains 1 protein kinase domain.

Contains 1 SH2 domain.

Contains 1 SH3 domain.
