Gap junctions formed by connexins 26 and 32 alone and in combination are differently affected by applied voltage.

LC Barrio, T Suchyna, T Bargiello… - Proceedings of the …, 1991 - National Acad Sciences
Gap junctions are formed by a family of homologous proteins termed connexins. Their channels
are dodecamers, and homomeric forms differ in their properties with respect to control by …

Molecular basis of calcium regulation in connexin-32 hemichannels

…, B Larrosa, D González, LC Barrio - Proceedings of the …, 2003 - National Acad Sciences
In addition to forming gap-junction channels, a subset of connexins (Cxs) also form functional
hemichannels. Most hemichannels are activated by depolarization, and opening depends …
