Functional Family	Tyrosine-protein kinase JAK2

Enzyme Information

2.7.10.2

Non-specific protein-tyrosine kinase.

based on mapping to UniProt P23458

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

-!- Unlike EC 2.7.10.1, this protein-tyrosine kinase does not have a transmembrane domain. -!- In the human genome, 32 non-specific protein-tyrosine kinases have been identified and these can be divided into 10 families. -!- Formerly EC 2.7.1.112.
