Identifier, protein and gene names [?]

Identifier
FLIW
Protein name
RecName: Full=Flagellar assembly factor FliW;
Gene name
fliW

Comments [?]

Function Acts as an anti-CsrA protein, binds CsrA and prevents it from repressing translation of its target genes, one of which is flagellin. Binds to flagellin and participates in the assembly of the flagellum.
Subunit Interacts with translational regulator CsrA and flagellin(s).
Subcellular location Cytoplasm.
Similarity Belongs to the FliW family.

Comments The ancestral operon is thought to be Fliw-CsrA, where CsrA is dedicated to controlling flagellar assembly and motility. Rounds of gene loss and re-acquisition in Gammaproteobacteria (which only rarely encode FliW) have lead to CsrA being repurposed for a larger role in translation control. See PubMed:25833324, Vakulskas et al., Microbiol. Mol. Biol. Rev. 79:193-224(2015) for a review.
