Extracellular antibodies are ideal research tools for cell-surface proteins.
No permeabilization/fixation because using extracellular antibodies allows you to work with live cells!
Benefits of live cell imaging:
✓ Monitor cell movement
✓ Study protein transport across the cell
✓ Investigate protein internalization
Latrophilins (Latrophilin1-3) are members of the adhesion G-protein coupled receptor subfamily. Like all GPCRs, Latrophilins have seven transmembrane domains and are distinguished by a large extracellular N-terminal tail and a large intracellular C-terminal tail. The N-terminus has several cell adhesion domains and undergoes proteolysis after synthesis, while the C-terminal has various consensus post-translational sites like phosphorylation and palmitoylation. In addition, Latrophilins undergo alternative splicing.
