This family represents the N-terminal part of a Neisseria protein, UniProtKB:Q5F5I0, PDB:3dee. It runs from residues 31-117 as a helical bundle with 4 main helices. \\From genomic context and the fold of the C-terminal part, it is suggested that this protein is involved in transcriptional regulation [1].

1: The structure of the first representative of Pfam family PF09836 reveals a two-domain organization and suggests involvement in transcriptional regulation.
