Function of Connexins in the Interaction between Glial and Vascular Cells in the Central Nervous System and Related Neurological Diseases

Figure 3

Schematic representation of connexins. Each Cx is a four-pass transmembrane (red frame) protein comprising two extracellular loops (EL1, purple region; EL2, green region) and a C-terminal cytoplasmic tail. The domains and motifs of connexins are depicted according to the size.
