Specificity/Sensitivity: cGAS (D1D3G) Rabbit mAb recognizes endogenous levels of total cGAS protein.
Source/Purification: Monoclonal antibody is produced by
immunizing animals with a synthetic peptide corresponding to
residues surrounding Ala19 of human cGAS protein.

Background: Cyclic GMP-AMP synthase (cGAS, MB21D1) is
an antiviral enzyme that produces the second messenger cyclicGMP-AMP (cGAMP) in response to cytoplasmic DNA (1,2). The
cGAS protein acts as a cytosolic DNA sensor that binds DNA
and produces the cGAMP second messenger from ATP and GTP
(1,2). cGAMP binds to and activates STING, a transmembrane
adaptor protein that is a critical component of the cellular innate
immune response to pathogenic cytoplasmic DNA (1-4). STING
is ubiquitously expressed and found predominantly in the ER
(3). Following activation, STING translocates with TBK1 to perinuclear endosomes (5). The TBK1 kinase phosphorylates and
activates interferon regulatory factors (IRFs) and NF-κB, which
leads to the induction of type I interferon and other immune
response genes (3-5).
