Dedicator Of Cytokinesis Protein (DOCK proteins)

Dock proteins, play a critical role in cell signaling and communication. 

Dock proteins are involved in the recruitment and assembly of different molecules at cell membrane sites, allowing for the transmission of signals and the coordination of cellular activities.

By providing a scaffold for protein-protein interactions, they help to organize and regulate signaling events, ensuring precise and efficient signal transduction within the cell.

Dock proteins contain protein-binding domains, allowing them to interact with other proteins and have localization to specific cellular locations.

These proteins bridge the gap between cell surface receptors and downstream signaling pathways.

When a signaling molecule, such as a hormone or growth factor, binds to a receptor on the cell membrane, dock proteins are recruited to the receptor complex. 

Dock proteins then serve as a platform for additional signaling molecules to bind and be activated, leading to downstream cellular responses.

Dock proteins are essential for various cellular processes of  cell growth and differentiation, immune responses, neuronal development, and cell migration. 

Dock proteins examples include Grb2 (Growth Factor Receptor-Bound Protein 2), which links receptor tyrosine kinases to downstream signaling cascades, and SH2 domain-containing adapter protein (SHC), which plays a role in insulin signaling and regulation of cell proliferation.
