Web25 feb. 2024 · Supplementary Figure S5: Microglia upregulate cGAS and STING after injury. mRNA expression of (A) cGAS and (B) STING in isolated microglia collected 2- and 24 h … cGAS is a 522 amino acid protein and a member of the nucleotidyltransferase family. N-terminal residues 1-212 are necessary to bind dsDNA. This region may contain two different DNA binding domains. C-terminal residues 213-522 contain part of the nucleotidyltransferase (NTase) motif and a Mab21 domain and are highly conserved in cGAS from zebrafish to humans. These regions are necessary to form the catalytic pocket for the cGAS substrates: GTP and ATP, and to perfor…
