additional information | Drosophila melanogaster | Waterproof is a Drosophila FAR with a preference for very long chain, saturated fatty acids of 24 and 26 carbons. In yeast cultures expressing Waterproof, tetracosanoyl-alcohol (24:0-OH) and hexacosanoyl-alcohol (26:0-OH) are identified by GC/MS analysis, unsaturated alcohols or alcohols of shorter chain-lengths are either absent or below the detection limit. Neither of these fatty alcohols is detected in the vector control yeast culture or the wat gene containing culture grown under non-inducing conditions | ? | - |

malfunction | in waterproof mutant embryos the formation of the outermost tracheal cuticle sublayer, the envelope is disrupted and the hydrophobic tracheal coating is damaged | Drosophila melanogaster |
physiological function | Waterproof, encoding a fatty acyl-CoA reductase (FAR), is essential for the gas filling of the tracheal tubes during Drosophila embryogenesis, and does not affect branch network formation or key tracheal maturation processes. A non-cell-autonomous waterproof function for the beginning of the tracheal gas filling process, overview. Waterproof plays a key role in tracheal gas filling by providing very long chain fatty alcohols that serve as potential substrates for wax ester synthesis or related hydrophobic substances that ultimately coat the inner lining of the trachea. The hydrophobicity in turn reduces the tensile strength of the liquid inside the trachea, leading to the formation of a gas bubble, the focal point for subsequent gas filling. Enzyme activity is specifically required for the tracheal liquid clearance (LC). Waterproof is essential for outer envelope formation of the tracheal cuticle | Drosophila melanogaster |
