Major calcium-binding protein of the Golgi which may have a role in calcium homeostasis (PubMed:7890746).

Acts as a non-receptor guanine nucleotide exchange factor which binds to and activates alpha subunits of guanine nucleotide-binding proteins (G proteins) (By similarity).

Interacts (via GBA motif) with guanine nucleotide-binding protein G(i) alpha subunits GNAI1, GNAI2 and GNAI3 with higher affinity for GNAI1 and GNAI3 than for GNAI2. Preferentially interacts with inactive rather than active GNAI3. Interaction with GNAI3 is inhibited when NUCB1 binds calcium, probably due to a conformational change which renders the GBA motif inaccessible.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
