    Summary
    The protein encoded by this gene belongs to the NF-kappa-B inhibitor family, which inhibit NF-kappa-B by complexing with, and trapping it in the cytoplasm. Phosphorylation of serine residues on these proteins by kinases marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF-kappa-B, which translocates to the nucleus to function as a transcription factor. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jul 2011]

    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.

    1. NR_040515.2 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) uses an alternate acceptor splice site at the second exon, and is alternatively spliced at the 3' end compared to variant 1. It is represented as non-coding due to the presence of an upstream ORF (with a strong Kozak signal) that is predicted to interfere with the translation of the downstream longer ORF; translation of the upstream ORF renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
