Summary Information
Automatically generated summary See sections below for more information	The gene Sema-2a is referred to in FlyBase by the symbol Dmel\Sema-2a (CG4700, FBgn0011260). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding. There is experimental evidence that it is involved in the biological process: adult behavior; axon guidance; visual behavior; flight behavior; synaptic target inhibition; salivary gland development; drinking behavior. 19 alleles are reported. The phenotypes of these alleles are annotated with: abdominal 1 RP3 neuron; abdominal 2 RP1 neuron; RP3 neuron; intersegmental nerve; abdominal 2 RP3 neuron; abdominal segmental nerve; imaginal disc; abdominal 1 RP1 neuron; transverse nerve; synapse. It has 4 annotated transcripts and 4 annotated polypeptides. Protein features are: Immunoglobulin subtype; Immunoglobulin-like; Immunoglobulin-like fold; Plexin-like fold; Plexin/semaphorin/integrin; Semaphorin/CD100 antigen; WD40/YVTN repeat-like-containing domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of low expression. Peak expression observed within 00-18 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system, adult heart, larval trachea, adult ovary. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult central nervous system, adult midgut, larval hindgut, adult fat body, larval salivary gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1629819_s_at completely aligns to an exonic region common to each of the 4 FlyBase-annotated transcript isoforms of Sema-2a. Gene sequence location is 2R:12387701..12420934.

Additional Descriptive Data
	Sema-2a expression is first detected at embryonic stage 10 in weak epidermal stripes. It is also found in the CNS starting in stage 15 in a restricted set of neurons. Beginning in stage 14, Sema-2a is expressed in a single ventral thoracic muscle fiber in the metathoracic segment. Expression occurs also in embryonic gonads and anterior sense organs.

Other Comments
	Mutants isolated in a screen of the second chromosome identifying genes affecting disc morphology. (Roch et al., 1998) Sema-2a prevents promiscuous and ectopic synapse formation. Relative balance of Sema-2a and Fas2 controls synaptogenesis. The relative balance of Sema-2a and the Netrins controls the choice of a specific target and the avoidance of a potential target. NetB and Sema-2a can both be repulsive for certain motor axons. (Winberg et al., 1998) Sema-2a can function as a inhibitory signal during target recognition, it inhibits two identified motoneuron growth cones RP3 and DC1 from forming normal synaptic terminal aborizations on their target muscles. RP1 and RP4 are unresponsive to contact with Sema-2a. (Matthes et al., 1995) Genetic analysis reveals that semaII is an essential gene required for both proper adult behaviour and survival. (Kolodkin et al., 1993)
