Docking protein 2 is a protein that in humans is encoded by the DOK2 gene.[1][2][3]
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.[3]
Interactions
DOK2 has been shown to interact with INPP5D[4] and TEK tyrosine kinase.[5][6]
