== Function ==
[https://www.uniprot.org/uniprot/DESK_BACSU DESK_BACSU] Member of the two-component regulatory system DesR/DesK, responsible for cold induction of the des gene coding for the Delta5 acyl-lipid desaturase. Acts as a sensor of the membrane fluidity. Probably activates DesR by phosphorylation.<ref>PMID:11285232</ref> <ref>PMID:11717295</ref> <ref>PMID:12207704</ref> <ref>PMID:14734164</ref> <ref>PMID:15090506</ref>
