    Protein Summary

    FFAS annotation: Hypothetical protein, cystatin-like fold, divergent member of PF14254 family (DUF4348)



    It is hypothetical protein BACCAC_01506 [Bacteroides caccae ATCC 43185] with the nearest FFAS (-38.3 score) predicted homolog 3sbu (also hypothetical ntf2-like protein).

    The PROFUNC however doesn't come up with NTF2 like assignment for that family. The link for some characteristics of the NTF2- like family based on the known 3sbu structure at:


    indicates a pure potential non-catalytic ligand-binding role for that target. An obvious consequence of that would be a regulation of protein-like binding partners to this target depending on the small ligand binding status.

    Attached figures shows the dimeric form as predicted by PISA server.
