We found that IRF5-dominant regions differed fundamentally from the IRF3- and IRF9-dominant regions: ISREs were rare, while the NFKB motif and special ISRE half-sites, such as 5'-GAGA-3' and 5'-GACA-3', were enriched

IFN-I can mediate ISG expression inmixed glial cell cultures (MGCs) via ISGF3-independent signaling pathways but with reduced efficiency, with delayed and prolonged kinetics, and is more dependent on STAT1 and STAT2 than IRF9; and 2) signaling pathways not involving STAT1, STAT2, or IRF9 play a minor role only in mediating IFN-alpha-stimulated genes expression in MGCs.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
