Docking protein 1 is a protein that in humans is encoded by the DOK1 gene.[1][2][3]

Docking protein 1 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. Docking protein 1 contains a putative pleckstrin homology domain at the amino terminus and ten PXXP SH3 recognition motifs. Docking protein 2 binds p120 (RasGAP) from CML cells. It has been postulated to play a role in mitogenic signaling.[4]

Interactions

DOK1 has been shown to interact with RET proto-oncogene,[5] SH2D1A,[6] LYN,[7][8] RAS p21 protein activator 1,[9][10][11] INPP5D,[9][7] CD117,[8] SHC1,[9] Abl gene[7][10] and TEC.[7][8]
