Docking protein 2 is a protein that in humans is encoded by the DOK2 gene.[5][6][7]

Function

The protein encoded by this gene is constitutively tyrosine phosphorylated in hematopoietic progenitors isolated from chronic myelogenous leukemia (CML) patients in the chronic phase. It may be a critical substrate for p210(bcr/abl), a chimeric protein whose presence is associated with CML. This encoded protein binds p120 (RasGAP) from CML cells.[7]

Interactions

DOK2 has been shown to interact with INPP5D[8] and TEK tyrosine kinase.[9][10]
