Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: morphogen activity; receptor binding; cytokine activity.
There is experimental evidence for 14 unique biological process terms, many of which group under: anatomical structure development; biological regulation; cellular process involved in reproduction; digestive tract development; localization; multicellular organismal reproductive process; organ morphogenesis; cell division; memory; cell-cell signaling; apical constriction; multicellular organismal process.
39 alleles are reported.
The phenotypes of these alleles are annotated with 39 unique terms, many of which group under: organ system; female germline cyst; embryonic segment; thoracic segment; organ system subdivision; imaginal precursor; embryonic abdomen; adult segment; multicellular structure; external compound sense organ.
It has 2 annotated transcripts and 2 annotated polypeptides.
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 00-06 hour embryonic stages.
