Tbp | TATA binding protein (Tbp) encodes a basal transcription factor required at most RNA Pol I and Pol II-transcribed genes. Traditionally thought to be recruited only to TATA box containing promoters, recent work shows that promoters with very weak TATA box consensus sequences also recruit the product of Tbp as a part of the multisubunit TFIID basal transcription factor or via the SAGA histone acetyltransferase complex.

tsg | Twisted gastrulation (tsg) encodes a BMP binding protein that makes a tripartite complex with the product of sog and a heterodimer formed with the products of dpp and scw. This complex is a favoured substrate for the product of tld, which processes the product of sog and liberates the heterodimer formed with the products of dpp and scw. (249 aa) |
