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; ribosome binding; translation initiation factor binding.
There is experimental evidence that it is involved in the biological process: neuron fate commitment; oogenesis; long-term memory; negative regulation of translation; axon midline choice point recognition.
39 alleles are reported.
No phenotypic data is available.
It has 7 annotated transcripts and 7 annotated polypeptides.
Protein features are: Armadillo-type fold; MIF4-like, type 1/2/3; eIF4-gamma/eIF5/eIF2-epsilon.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of high expression.
Peak expression observed at stages throughout embryogenesis, at stages throughout the larval period, at stages throughout the pupal period, in adult female stages.
