grh | Protein grainyhead; Grainy head (grh) encodes the founding member of a highly conserved family of transcription factors essential for embryonic development. It is both a transcriptional activator and repressor, responsible for the proper expression of many genes primarily involved in epithelial cell fate, barrier formation, wound healing, tube morphogenesis and proliferation of larval neuroblasts; Belongs to the grh/CP2 family. Grainyhead subfamily. (1333 aa) | ||||
vn | Vein (vn) encodes a secreted neuregulin-like EGFR ligand. It has weaker intrinsic activity, and a lower receptor affinity, than the TGFalpha-like ligand encoded by spi. It has roles in growth and patterning of tissues including muscle, midgut, ovary, trachea, glia, eye, leg, and wing. (623 aa) |
