Regulation of connexin degradation as a mechanism to increase gap junction assembly and function.

Abstract excerpt

Connexins, the integral membrane protein constituents of gap junctions, are degraded at a rate (t(12) = 1.5-5 h) much faster than most other cell surface proteins. Although the turnover of connexins has been shown to be sensitive to inhibitors of either the lysosome or of the proteasome, how connexins are targeted for degradation and whether this process can be regulated to affect intercellular communication is...
