Interactioni
Subunit structurei
Interacts (via GBA motif) with guanine nucleotide-binding protein G(i) alpha subunit GNAI3 (PubMed:21653697). Preferentially interacts with inactive rather than active GNAI3 (PubMed:21653697). Interaction with GNAI3 is inhibited when NUCB2 binds calcium, probably due to a conformational change which renders the GBA motif inaccessible (PubMed:21653697). Binds to the postmitotic growth suppressor NDN; coexpression abolishes NUCB2 secretion (By similarity).
