General annotation (Comments)

Function

Member of the two-component regulatory system MprB/MprA which contributes to maintaining a balance among several systems involved in stress resistance and is required for establishment and maintenance of persistent infection in the host. Functions as a transcriptional regulator that recognizes a 19-bp nucleotide motif comprizing two loosely conserved 8-bp direct DNA-binding motif repeats separated by a 3-bp spacer region By similarity.

Subcellular location

Cytoplasm Potential.

Post-translational modification

Phosphorylated and dephosphorylated by MprB By similarity.

Sequence similarities

Contains 1 response regulatory domain.

Sequence caution

The sequence AFP41777.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
