DOCK2, a key protein, regulates immune and non-immune cells. Its dysregulation is linked to diseases like cancer and fibrosis, offering potential therapeutic targets.
Area of Science:
- Molecular biology
- Cellular signaling
- Immunology
Background:
- DOCK2 (Dedicator of cytokinesis 2) is a Guanine nucleotide Exchange Factor (GEF).
- It is widely expressed, particularly in immune cells, and involved in cell functions.
- DOCK2 also impacts non-immune cells, relevant to various pathologies.
Purpose of the Study:
- To review DOCK2's structure, function, and roles in disease.
- To provide a basis for developing targeted therapies for DOCK2-related disorders.
Main Methods:
- Systematic literature review.
- Summarized DOCK2's molecular features, expression, and regulatory pathways (Rac-dependent and independent).
- Examined DOCK2's implications in inflammation, cancer, fibrosis, and related conditions.
Main Results:
- DOCK2 regulates immune cell proliferation, differentiation, migration, and cytokine secretion via Rac activation.
- DOCK2 is implicated in glial cells and vascular smooth muscle cells.
- Its dysregulation is associated with inflammatory diseases, cancer, atherosclerosis, idiopathic pulmonary fibrosis, and obesity.
Conclusions:
- DOCK2 is crucial for immune and non-immune cellular processes through Rac and non-Rac pathways.
- DOCK2 dysregulation is linked to numerous diseases.
- Understanding DOCK2's regulatory networks may uncover new therapeutic targets.
