Summary: This gene encodes a member of the HIN-200 (hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeats) family of cytokines. The encoded protein contains domains involved in DNA binding, transcriptional regulation, and protein-protein interactions. The protein localizes to the nucleoplasm and nucleoli, and interacts with p53 and retinoblastoma-1. It modulates p53 function, and inhibits cell growth in the Ras/Raf signaling pathway. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2011]

The authors show that IFI16 is in complex with the H3K9 methyltransferase SUV39H1 and GLP and recruits them to the human herpesvirus 8 genome during de novo infection and latency. The resulting depositions of H3K9me2/me3 serve as a docking site for the heterochromatin-inducing HP1alpha protein leading into the IFI16-dependent epigenetic modifications and silencing of the virus lytic genes.

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.

NM_001206567.2 → NP_001193496.1 gamma-interferon-inducible protein 16 isoform 1

Status: REVIEWED

Description

Transcript Variant: This variant (1) lacks an in-frame exon in the 5' coding region and has an additional in-frame exon in the 3' coding region, compared to variant 2. The additional exon is described as exon 7a in PMID:9718316. The resulting isoform (1) is of the same size but lacks a segment in the N-terminal region and has an additional segment in the C-terminal region, compared to isoform 2. Note the CDS was annotated to initiate translation from an in-frame downstream AUG, as it is flanked by a strong Kozak signal, and is better conserved than the upstream AUG located 4 codons upstream.
