Comments [?]

Function A probable RNA chaperone. Forms a complex with KhpA which binds to cellular RNA and controls its expression. Plays a role in peptidoglycan (PG) homeostasis and cell length regulation.
Subunit Forms a complex with KhpA.
Subcellular location Cytoplasm.
Domain Has an N-terminal Jag-N domain and 2 RNA-binding domains (KH and R3H).
Similarity Belongs to the KhpB RNA-binding protein family.
