Organism
Drosophila pseudoobscura pseudoobscura
Function
Required for homeostatic regulation of sleep under normal conditions and after sleep deprivation. Important regulator of the Sh K(+) channel, acting as a signaling molecule that connects sleep drive to lowered membrane excitability, possibly by enhancing K(+) channel activity and thus reducing neuronal excitability (By similarity).
Similarity
Belongs to the quiver family.
