Summary
This genomic region represents the 5' regulatory region of the interferon alpha and beta receptor subunit 1 (IFNAR1) gene, which encodes an antiviral factor that may play a role in interferon immunity in coronavirus disease 2019 (COVID-19). This region functions as a promoter that drives IFNAR1 expression. It includes a binding site for the high mobility group box 1 (HMGB1) protein, which together with poly(ADP-ribose) polymerase 1 (PARP-1), functions as a cofactor for IFNAR1 transcription, and where suppression of PARP-1 by hepatitis B virus infection can lower IFNAR1 expression. Two subregions marked by the H3K27ac histone modification were also shown to be active enhancers by ChIP-STARR-seq in human embryonic stem cells. Multiple polymorphisms have been found within this promoter, including a SNP (rs2850015) that affects promoter activity in HepG2 liver carcinoma cells, a GT(n) variable number tandem repeat (rs36158718) that affects promoter activity in 293T embryonic kidney cells, and a SNP (rs2843710) that affects promoter activity in THP-1 monocytes infected with enterovirus 71. This locus also includes two accessible chromatin subregions that were validated as enhancers based on their ability to activate an origin of replication minimal core promoter by the ATAC-STARR-seq (assay for transposase-accessible chromatin with self-transcribing active regulatory region sequencing) massively parallel reporter assay (MPRA) in GM12878 lymphoblastoid cells.

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.
