Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: growth factor activity.
There is experimental evidence that it is involved in the biological process: torso signaling pathway; terminal region determination; ring gland development; imaginal disc-derived wing vein morphogenesis; maternal specification of dorsal/ventral axis, oocyte, soma encoded.
104 alleles are reported.
The phenotypes of these alleles are annotated with 33 unique terms, many of which group under: adult segment; organ system subdivision; organ system; adult mesothoracic segment; presumptive embryonic/larval nervous system; primordium; late extended germ band embryo; presumptive embryonic/larval peripheral nervous system; embryonic/larval tracheal system; extended germ band embryo.
It has one annotated transcript and one annotated polypeptide.
Protein features are: CHRD; Chordin; von Willebrand factor, type C.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression.
Peak expression observed within 00-06 hour embryonic stages.
