1.A.24.1.14
Gap junction protein B4, GJB4, or Cx30.3 of 266 aas and 4 TMSs. Small molecules and ions diffuse from one cell to a neighboring cell via the central pore in these dodecameric channels. Mutation can cause a familial form of hypertrophic cardiomyopathy (HCM) and therefore could be a target for the treatment of cardiac hypertrophy and dysfunction (Okamoto et al. 2020).
