ARF鸟苷酸交换因子BIG1抗体产品介绍：background: Guanine nucleotide-exchange proteins (GEPs) accelerate replacement of bound GDP with GTP and thereby activate ADP-ribosylation factors (ARFs), a family of guanine nucleotide-binding proteins that play an important role in intracellular vesicular trafficking. GEPs comprise two major families, large GEPs that are inhibited by brefeldin A (BFA), a protein that effects Golgi structure and a group of smaller GEPs that are insenstive to BFA. Two genes for GEPs found on human chromosomes 8 and 20 encode BFA sensitive GEPs designated BIG1 and BIG2. Both GEPS contain a sec7 domain that is responsible for their brefeldin inhibition and also their catalytic activity. In vivo, BIG1 and BIG2 exist in macromolecular complexes that move between the Golgi membranes and cytosol. BIG2 associates with PKA ARF鸟苷酸交换因子BIG1抗体regulatory subunits, implying that BIG2 may act as an A kinase-anchoring protein (AKAP) that could coordinate the cAMP and ARF regulatory pathways. Function: BIG1 is a brefeldin A-inhibited guanine nucleotide exchange protein (GEP) that activates ADP-ribosylation factor (ARF) GTPases and functions in vesicle formation from Golgi membranes. Subunit: Homodimer (Probable). Interacts with BIG1; both proteins are probably part of the same or very similar macromolecular complexes. Interacts with FKBP2, DPY30, MYO9B, PRKAR1A, PRKAR2A, PPP1CC and PDE3A. Interacts with KANK1; however, colocalization cannot be experimentally confirmed. Interacts with NCL, FBL, NUP62 and U3 small nucleolar RNA. Subcellular Location: Cytoplasm. Cytoplasm, perinuclear region. Golgi apparatus. Golgi apparatus, trans-Golgi network (By similarity). Nucleus. Nucleus, nucleolus. Nucleus matrix. Membrane. Note=Translocates from cytoplasm to membranes and nucleus upon cAMP treatment.ARF鸟苷酸交换因子BIG1抗体 Tissue Specificity: Expressed in placenta, lung, heart, brain, kidney and pancreas.
