Biochem/physiol Actions

ADP ribosylation factor guanine nucleotide exchange factor 2 (ARFGEF2) activates ADP-ribosylation factors (ARFs) by exchanging guanosine diphosphate (GDP) with guanosine triphosphate (GTP). It aids in the release of type I tumor necrosis factor receptor (TNFR1) from human umbilical vein endothelial cells. Mutation in the ARFGEF2 gene has been linked to microcephaly and periventricular heterotopia.

General description

ADP ribosylation factor guanine nucleotide exchange factor 2 (ARFGEF2) possesses a Sec7 domain which is crucial for its activity. This protein is expressed in the brain and the gene encoding it is localized on human chromosome 20.

Immunogen

Synthetic peptide corresponding to a region derived from internal residues of human ADP-ribosylation factor guanine nucleotide-exchange factor 2 (brefeldin A-inhibited)

Physical form

Rabbit IgG in pH7.3 PBS, 0.05% NaN₃, 50% Glycerol.

Specificity

The antibody detects endogenous levels of total ARFGEF2 protein.
