Secondary Information

Protein Function One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell.
Biochemical Properties gap junction proteins which are arranged in groups of 6 around a central pore to form a connexon, a component of the gap junction intercellular channel.

Significance of PTMs Two important modulators are dopamine and adenosine which control phosphorylation and dephosphorylation. Cx35/Cx36 remains in a dephosphorylated (uncoupled) state under bright lighting conditions. High-illuminant light inhibits ocular growth through the uncoupling of retinal gap junctions.Light-directed Cx35/36 (de)phosphorylation has been described to be regulated by dopamine signaling (effect: dephosphorylation/uncoupling) and and adenosine signaling (effect: phosphorylation/coupling).
