This family represents a domain of approximately 90 residues that is tandemly repeated within interferon-induced 35 kDa protein (IFP 35) and the homologous N-myc-interactor (Nmi). This domain mediates Nmi-Nmi protein interactions and subcellular localisation [1].

1: Interferon-inducible Myc/STAT-interacting protein Nmi associates with IFP 35 into a high molecular mass complex and inhibits proteasome-mediated degradation of IFP 35. Chen J, Shpall RL, Meyerdierks A, Hagemeier M, Bottger EC, Naumovski L; J Biol Chem 2000;275:36278-36284. PMID:10950963
