Its putative 30 involvements in intracellular calcium (Ca2+) homeostasis have however never been 31 phenotypically characterized in any model organism. We have analyzed an adult-viable mutant 32 that completely disrupts the G protein α-subunit Binding and Activating (GBA) motif of 33 Drosophila Nucleobindin-1 (dmNUCB1).
