Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: beta-1,4-mannosylglycolipid beta-1,3-N-acetylglucosaminyltransferase activity; acetylglucosaminyltransferase activity.
There is experimental evidence that it is involved in the biological process: glycosphingolipid biosynthetic process; morphogenesis of follicular epithelium; ovarian follicle cell-cell adhesion; border follicle cell migration; maintenance of polarity of follicular epithelium; germarium-derived egg chamber formation; optic lobe placode formation; ovarian follicle cell development.
8 alleles are reported.
The phenotypes of these alleles are annotated with: follicle cell; dorsal appendage; ovary; lamina plexus.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Glycosyl transferase, family 31.
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 hour embryonic stages.
