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) | ||||
smg | Smaug (smg) encodes the founding member of the SMAUG family of sequence-specific RNA-binding proteins. During the maternal-to-zygotic transition in early embryos, the smg product inhibits the translation and induces the degradation of hundreds of maternal mRNAs by recruitment of the CCR4-NOT deadenylase complex, thereby controlling embryonic patterning, activation of zygotic transcription, and early embryonic cell cycles.
