Chains	Accession	Name	Description	Comments	Source
A, B	PF00249	Myb-like DNA-binding domain (Myb_DNA-binding)	Myb-like DNA-binding domain	This family contains the DNA binding domains from Myb proteins, as well as the SANT domain family [1].	Domain
A, B	PF00072	Response regulator receiver domain (Response_reg)	Response regulator receiver domain	This domain receives the signal from the sensor partner in bacterial two-component systems. It is usually found N-terminal to a DNA binding effector domain.	Domain
