EC 2.7.10.2: Non-specific protein-tyrosine kinase

Reaction catalysed:
ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
Comments:
  • 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.
Systematic name:
ATP:[protein]-L-tyrosine O-phosphotransferase (non-specific)
