CC -!- FUNCTION: Required for homeostatic regulation of sleep under normal
CC conditions and after sleep deprivation. Important regulator of the Sh
CC K(+) channel, acting as a signaling molecule that connects sleep drive
CC to lowered membrane excitability, possibly by enhancing K(+) channel
CC activity and thus reducing neuronal excitability.
CC {ECO:0000269|PubMed:18635795}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor, GPI-anchor.
CC -!- TISSUE SPECIFICITY: Enriched in brain and head.
CC {ECO:0000269|PubMed:18635795}.
CC -!- PTM: N-glycosylated. {ECO:0000269|PubMed:18635795}.
CC -!- DISRUPTION PHENOTYPE: Both daytime and nighttime sleep are severely
CC reduced in both males and females. A small percentage of flies (around
CC 9%) do not sleep at all. A moderate reduction has minimal effects on
CC baseline sleep but markedly reduces the amount of recovery sleep after
CC sleep deprivation. Mutants have impaired Sh-dependent K(+) current.
CC {ECO:0000269|PubMed:18635795}.
CC -!- SIMILARITY: Belongs to the quiver family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL90233.1; Type=Miscellaneous discrepancy; Note=Several sequencing errors.; Evidence={ECO:0000305};
