beat expression is first observed in a subset of CNS neurons. It is thought to be expressed by all motor neurons and exclusively by motor neurons. Expression peaks at stage 13, drops to a lower level after stage 14 and continues through stage 17. beat is expressed at higher levels in some motor neurons than others. For example, expression is stronger in RP1 and RP3 than in aCC.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Identification: Ethyl methanesulfonate screen for mutations that disrupt the larval visual system: enumeration or adhesion of the larval photoreceptor cells.
beat-Ia is required for the selective defasciculation of motor neurons at choice points along the major motor nerves. Mutant phenotype can be suppressed by mutations in Fas2 and Con suggesting beat-Ia provides an antiadhesive function. Rescue and ectopic expression experiments support the model that beat-Ia protein is secreted by motor axons where it functions to regulate their selective defasciculation at specific choice points.
