Ubx | Homeotic protein ultrabithorax; Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Binds the consensus region 5'-TTAAT[GT][GA]-3'. This homeotic protein controls development of the cells in the posterior thoracic and first abdominal segments. It activates the synthesis of the decapentaplegic (DPP) growth factor; Belongs to the Antp homeobox family. (389 aa) | ||||
SuUR | Protein suppressor of underreplication; Required for underreplication of DNA, which is found in many late replicating euchromatic regions of salivary gland polytene chromosomes. Functions by promoting the localization and retention of Rif1 to active DNA replication forks where Rif1 inhibits replication fork progression. Controls chromatin organization in polytene chromosomes. (962 aa) |
