Source was larval brain of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

Fmr1 protein suppresses Dscam translation, but does not affect the level of Dscam RNA.

Source was larval brain of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

Fmr1 protein binds multiple Dscam isoforms with no substantial isoform bias observed.

Isoforms of Dscam RNA bound to Fmr1 protein were identified by high throughput pyrosequencing.

Source was larval brains of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

Fmr1 null mutations result in a 49% increase in Dscam1 protein levels.
