Strikingly, 25 of the 26 overlapping genes
were down-regulated (94%), while only spicule matrix protein SM30 was induced by seawater acidification in multiple studies.
There is evidence that there are overlapping genes
that run on opposite strands, encoding proteins of different functions.
The researchers next established that HAR1 includes two overlapping genes
Most genetic studies have failed to find overlapping genes
in the two disorders, but recent data suggest there might be some interactions among gene products, she noted.
Structural constraints imposed by overlapping genes
transcribed on opposite DNA strands or by overlapping genes
that use coding information from the same DNA sequence (Farr and Goodfellow 1992)
