    Summary
    The protein encoded by this gene contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. Several alternatively spliced transcript variants have been noted for this gene, however, not all are likely to encode viable protein products. [provided by RefSeq, Sep 2008]

    2. Study found that RNF121 was less expressed in tumor tissues than adjacent normal tissues of renal cell carcinoma (RCC) patients. Overexpression of RNF121 inhibited the growth of human RCC cells in vivo. Moreover, RNF121 impeded the proliferation, migration and invasion of human RCC cells in vitro. In addition, RNF121 was found to activate NF-kappaB signaling pathway via promoting IkappaBalpha degradation in RCC 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.

    RNA

    1. NR_024147.2 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (2) is missing an internal coding exon compared to transcript variant 1. If translation initiates at the same codon as used in variant 1, then this results in a frame-shift and premature translation termination, rendering the transcript susceptible to nonsense-mediated mRNA decay (NMD). Although a putative alternate AUG site is observed in a different frame downstream of the standard AUG site, it is not likely to be used because it is located within the short ORF available with the standard AUG site (as defined by variant 1). Therefore, the transcript is represented as a non-protein-coding RefSeq.

    2. NR_024148.2 RNA Sequence

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) is missing an internal coding exon and also includes an additional exon compared to transcript variant 1. This results in a frame-shift and premature translation termination, rendering the transcript susceptible to nonsense-mediated mRNA decay (NMD). There are no other likely translation initiation sites and so the transcript is represented as a non-protein-coding RefSeq.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_194452.1: Suppressed sequence

      Description
      NM_194452.1: This RefSeq was permanently suppressed because it was annotated with an overlapping downstream ORF when an upstream ORF existed. However, use of the upstream AUG will render this transcript susceptible to nonsense-mediated mRNA decay (NMD).

    2. NM_194453.1: Suppressed sequence

      Description
      NM_194453.1: This RefSeq was permanently suppressed because it was annotated with an overlapping downstream ORF when an upstream ORF existed. However, use of the upstream AUG will render this transcript susceptible to nonsense-mediated mRNA decay (NMD).
