Activity summary

DOK1 also known as Docking protein 1 or Downstream of tyrosine kinase 1 is an adaptor protein involved in the signal transduction pathways. This protein weighs approximately 62 kDa and is primarily expressed in hematopoietic cells. While DOK1 lacks enzymatic activity it plays an important role in cellular processes by providing a scaffold for various signaling molecules. It helps to modulate downstream signaling events by interacting with receptor tyrosine kinases and other proteins through its multiple binding domains.

Biological function summary

DOK1 operates as a negative regulator in signal transduction functioning as part of a larger signaling complex. The protein associates with different cellular components forming interactions that influence cell communication and immune response. DOK1 often interacts with proteins like RasGAP and Nck which helps in mediating signals that can affect cell growth differentiation and apoptosis. Its role as a docking station for other proteins allows it to influence cellular homeostasis.

Pathways

DOK1 influences the Ras and MAP kinase signaling pathways. It inhibits the Ras pathway by binding with and recruiting RasGAP leading to the inactivation of Ras an important player in cell proliferation. Additionally DOK1 modulates the JAK/STAT pathway by affecting cytokine signaling and immune regulation. These interactions are significant for controlling cellular responses and maintaining balance in cell signaling networks.

Associated diseases and disorders

DOK1 is implicated in conditions like leukemia and autoimmune diseases. Aberrant DOK1 expression or malfunction disrupts normal signal transduction contributing to the pathogenesis of these disorders. In leukemia altered DOK1 activity can affect its interactions with proteins such as RasGAP leading to unchecked cell growth and survival. Similarly in autoimmune diseases DOK1's regulatory effect on JAK/STAT signaling might be compromised impacting immune cell function and response.
