Enables G-protein alpha-subunit binding activity; calcium ion binding activity; and guanyl-nucleotide exchange factor activity. Involved in regulation of protein targeting and small GTPase-mediated signal transduction. Located in Golgi apparatus; cytoplasmic vesicle; and extracellular space. Is extrinsic component of Golgi membrane. Orthologous to human NUCB1 (nucleobindin 1); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 6-propyl-2-thiouracil; acrylamide.
[Tetrachlorodibenzodioxin binds to AHR protein] which results in increased expression of NUCB1 mRNA and [Tetrachlorodibenzodioxin co-treated with Ethinyl Estradiol] results in increased expression of NUCB1 mRNA
[Acrolein co-treated with methacrylaldehyde co-treated with alpha-pinene co-treated with Ozone] results in increased oxidation of NUCB1 mRNA and [Air Pollutants results in increased abundance of [Acrolein co-treated with methacrylaldehyde co-treated with alpha-pinene co-treated with Ozone]] which results in increased oxidation of NUCB1 mRNA
[[Hydroxyl Radical results in increased oxidation of dimethylselenide] which results in decreased expression of NUCB1-AS1 mRNA] which results in decreased expression of NUCB1 mRNA
[[Hydroxyl Radical results in increased oxidation of dimethylselenide] which results in decreased expression of NUCB1-AS1 mRNA] which results in decreased expression of NUCB1 mRNA
[LDN 193189 co-treated with 4-(5-benzo(1 and 3)dioxol-5-yl-4-pyridin-2-yl-1H-imidazol-2-yl)benzamide co-treated with FGF2 protein] results in increased expression of NUCB1 protein
A systematic analysis of 40 random genes in cultured vascular smooth muscle subtypes reveals a heterogeneity of gene expression and identifies the tight junction gene zonula occludens 2 as a marker of epithelioid "pup" smooth muscle cells and a participant in carotid neointimal formation.
