Gene details (from Flybase) 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: axon guidance.
14 alleles are reported.
The phenotypes of these alleles are annotated with: medial longitudinal fascicle; RP3 neuron; SNa; intersegmental nerve.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Cell surface receptor IPT/TIG; Immunoglobulin E-set; Immunoglobulin-like fold; Plexin; Plexin, cytoplasmic RasGAP domain; Plexin-like fold; Plexin/semaphorin/integrin; Rho GTPase activation protein; Semaphorin/CD100 antigen; WD40/YVTN repeat-like-containing domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 00-06 and 12-18 hour embryonic stages.
