Histone modification HNRNPA2B1 JMJD6 Downstream Gene Direct Enhancement m6A modification IFI16 IFI16 hnRNPA2B1 : m6A sites
m6A Modification:
m6A Regulator Heterogeneous nuclear ribonucleoproteins A2/B1 (HNRNPA2B1) READER
m6A Target Gamma-interferon-inducible protein 16 (IFI16)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type Histone modification (HistMod)
Epigenetic Regulator Bifunctional arginine demethylase and lysyl-hydroxylase JMJD6 (JMJD6) ERASER View Details
Regulated Target Heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1) View Details
Crosstalk Relationship Histone modification  →  m6A Enhancement
Crosstalk Mechanism histone modification directly impacts m6A modification through recruiting m6A regulator
Crosstalk Summary the arginine demethylase JMJD6 promotes the demethylation of HNRNPA2B1 at Arg226 and activates its translocation to cytoplasm, which further magnifies the expression of CGAS, Gamma-interferon-inducible protein 16 (IFI16), and STING
In-vitro Model
RAW 264.7 Mouse leukemia Mus musculus CVCL_0493
HEK293 Normal Homo sapiens CVCL_0045
HEK293T Normal Homo sapiens CVCL_0063
In-vivo Model Hnrnpa2b1fl/fl and Hnrnpa2b1fl/flLyz2-Cre+ mice were infected with 1×108 plaque-forming units (PFU) of HSV-1 viruses intraperitoneally. Serum IFN-beta concentrations were determined by enzyme-linked immunosorbent assay (ELISA) kit. HSV-1 titers were determined by plaque assays using homogenates from brains of infected mice.
