1 A potential role for the phospholipase D2-aquaporin-3 signaling module in early keratinocyte differentiation: production of a phosphatidylglycerol signaling lipid. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
2 As PLD2 can utilize the physiological alcohol glycerol to form phosphatidylglycerol (PG), we hypothesized that AQP3 provides glycerol to PLD2 for PG synthesis, which then modulates keratinocyte function. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
3 As PLD2 can utilize the physiological alcohol glycerol to form phosphatidylglycerol (PG), we hypothesized that AQP3 provides glycerol to PLD2 for PG synthesis, which then modulates keratinocyte function. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
4 As PLD2 can utilize the physiological alcohol glycerol to form phosphatidylglycerol (PG), we hypothesized that AQP3 provides glycerol to PLD2 for PG synthesis, which then modulates keratinocyte function. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
5 Acidic medium inhibits AQP3 transport activity; both glycerol uptake and PG synthesis were inhibited by low versus physiological pH. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
6 Thus, our results support the idea that AQP3 supplies PLD2 with glycerol for synthesizing PG, a lipid signal that promotes early keratinocyte differentiation. Phosphatidylglycerols aquaporin 3 (Gill blood group) Homo sapiens
