DOK2 (docking protein 2)

Gene

• Entrez ID: 9046
• Gene name: Docking protein 2
• Gene symbol: DOK2
• Synonyms (NCBI Gene): p56DOK, p56dok-2
• Chromosome: 8
• Chromosome location: 8p21.3
• Summary: 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 wh
