connexon

Examples of connexon in the following topics:

• Gap Junctions

  • Each of these half channels is called a connexon. 
  • Each connexon is made up of six symmetrical integral membrane protein units called connexins. 
  • The cytoplasmic end of each connexon can also be closed, if necessary.

• Intercellular Junctions

  • Gap junctions develop when a set of six proteins (called connexins) in the plasma membrane arrange themselves in an elongated doughnut-like configuration called a connexon.
  • When the pores ("doughnut holes") of connexons in adjacent animal cells align, a channel between the two cells forms.
