Gene Gene information from NCBI Gene database.
Entrez ID 64135
Gene name Interferon induced with helicase C domain 1
Gene symbol IFIH1
Synonyms (NCBI Gene)
AGS7HlcdIDDM19IMD95MDA-5MDA5RLR-2SGMRT1
Chromosome 2
Chromosome location 2q24.2
Summary IFIH1 encodes MDA5 which is an intracellular sensor of viral RNA that triggers the innate immune response. Sensing RNA length and secondary structure, MDA5 binds dsRNA oligonucleotides with a modified DExD/H-box helicase core and a C-terminal domain, thus
