Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: protein tyrosine phosphatase activity; transmembrane receptor protein tyrosine phosphatase activity.
There is experimental evidence that it is involved in the biological process: motor axon guidance; defasciculation of motor neuron axon.
23 alleles are reported.
The phenotypes of these alleles are annotated with: intersegmental nerve; abdominal segmental nerve.
It has 5 annotated transcripts and 5 annotated polypeptides.
Protein features are: Fibronectin type III domain; Fibronectin, type III; Immunoglobulin subtype; Immunoglobulin-like; Immunoglobulin-like fold; Protein-tyrosine phosphatase, active site; Protein-tyrosine phosphatase, receptor/non-receptor type; Protein-tyrosine/Dual-specificity phosphatase.
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 06-18 hour embryonic stages, at stages throughout the pupal period.
