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.
Its molecular function is unknown.
There is experimental evidence that it is involved in the biological process: spermatid development; sperm motility; spermatogenesis.
15 alleles are reported.
The phenotypes of these alleles are annotated with: investment cone; pre-elongation spermatid; elongation stage spermatid; major mitochondrial derivative; cystic bulge; waste bag; individualization stage spermatid; minor mitochondrial derivative; spermatozoon.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Sad1/UNC-like, C-terminal.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of no expression detected.
Peak expression observed at stages throughout the pupal period, in adult male stages.
