DEVR_MYCTU Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response (PubMed:15033981). Regulates an approximately 48-member regulon (PubMed:12953092, PubMed:11416222, PubMed:15033981, PubMed:18400743). When phosphorylated binds and activates the promoter of DevR regulon genes in response to hypoxia (PubMed:18359816, PubMed:21764934, PubMed:28977726). The presence of target DNA increases stability of phospho-DevR in vitro (PubMed:28977726). Activates its own transcription under hypoxic but not aerobic conditions, probably binds as a dimer to tandem binding sites within the devR and hspX promoters (PubMed:18359816). Accepts a phosphate group from DevS (DosS) and from DosT (PubMed:15033981, PubMed:15073296, PubMed:21764934, PubMed:28977726). Does not regulate transcription of dosT (PubMed:19487478).[1][2][3][4][5][6][7][8][9]
