gro | Groucho (gro) encodes a global developmental co-repressor in conjunction with manifold DNA-binding repressor partner proteins, which tether it to target promoters. It functions downstream of key signaling pathways such as Wg/Wnt and Dpp/TGF-beta. Notably, phosphorylation of the product of gro in response to MAPK activation weakens its repressor capacity.

Ste:CG33237 | Stellate protein CG33237; Unknown. In males lacking the Y chromosome, its strong overexpression leads to the appearance of proteinaceous star-shaped crystals in the primary spermatocytes causing meiotic drive, possibly by interfering with normal casein kinase 2 activity. (172 aa) |
