Table 7 Differences in phospholipids associated with connexin junctional plaques.
From: Connexin channels and phospholipids: association and modulation
Plaque | Headgroup | Linkage | Carbon atoms (number) | Saturation |
|---|---|---|---|---|
Cx26 | PC, PE, PA, PI, PS. Approx. 50% anionic. | More ether-linkages than unique to Cx32. | Range 28 to 44. Mean 39. Median 40. | Broad distribution. |
Cx32 | PC, PE, PA, PI, PS. More anionic than Cx26. | Fewer ether-linkages than unique to Cx26. | Range 22 to 38. Mean 31. Median 32. | Broad distribution, shorter chains more saturated. |
Cx26 and Cx32 | PC, PE, PA. No unique species of PI and PS. Predominantly zwitterionic. | Fewer ether-linkages than unique to Cx26, similar to Cx32. | Range 30 to 38. Mean 35. Median 36. | Broad distribution, shorter chains more saturated. |
