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.

ro | Homeobox protein rough; Required to establish the unique cell identity of photoreceptors R2 and R5 and consequently for ommatidial assembly in the developing eye imaginal disk. Repression of expression in R8 photoreceptor by senseless (sens) is an essential mechanism of R8 cell fate determination. (350 aa) |
