Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: vitellogenin receptor activity.
It is reported to be involved in the biological process: vitellogenesis; oogenesis.
42 alleles are reported.
The phenotypes of these alleles are annotated with: stage S13 oocyte; yolk granule; stage S10 oocyte; chorion; egg; coated pit; stage S14 oocyte; coated vesicle.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: EGF calcium-binding; EGF-like calcium-binding; EGF-like calcium-binding, conserved site; EGF-like region, conserved site; EGF-type aspartate/asparagine hydroxylation site; Epidermal growth factor-like; Epidermal growth factor-like, type 3; LDLR class B repeat; Low-density lipoprotein (LDL) receptor class A repeat; Low-density lipoprotein (LDL) receptor class A, conserved site; Six-bladed beta-propeller, TolB-like.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of extremely low expression.
Peak expression observed within 00-06 hour embryonic stages, in adult female stages.
