Intestinal gene expression in different physiological conditions There is not condition-dependent expression data available for this gene.
Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: calcium-dependent phospholipid binding.
There is experimental evidence that it is involved in the biological process: regulation of neurotransmitter secretion; regulation of synaptic plasticity.
16 alleles are reported.
The phenotypes of these alleles are annotated with: NMJ bouton; neuromuscular junction; motor neuron.
It has one annotated transcript and one annotated polypeptide.
Protein features are: C2 calcium-dependent membrane targeting; C2 calcium/lipid-binding domain, CaLB; C2 membrane targeting protein; C2 region; Synaptotagmin.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of extremely low expression.
Peak expression observed within 12-24 hour embryonic stages, during early larval stages, at stages throughout the pupal period, in adult male stages.
