产品描述:
Cyclic GMP-AMP (cGAMP) synthase (cGAS) (161-522) is a truncated form of cGAS (Item No. 22810) that contains the nucleotidyltransferase and Mab21 domains.{43137} cGAS is a nucleotidyltransferase located in the cytosol that acts as a cytosolic DNA sensor to detect foreign DNA from microbial pathogens as part of the innate immune response.{22400,22401} Upon binding to cytosolic DNA, cGAS produces the cyclic dinucleotide second messenger cGAMP, which activates stimulator of interferon genes (STING), leading to activation of the type I interferon (IFN) pathway.{22400,22401,39161} In vitro, fibroblasts, macrophages, and dendritic cells isolated from cGAS knockout (cGAS-/-) mice do not produce type I IFNs following DNA transfection or DNA virus infection.{39163} Similarly, cells containing a frame-shift mutation in the cGAS locus fail to mount an immune response to HIV and other retroviruses.{39164} In vivo, cGAS-/- mice infected with herpes simplex virus 1 (HSV-1) have lower levels of IFN-α and IFN-β, shorter survival times, and higher post-mortem levels of HSV-1 in the brain.{39163}
