    Summary
    Enables RNA binding activity. Predicted to be involved in several processes, including IRES-dependent viral translational initiation; RNA metabolic process; and protein localization to cytoplasmic stress granule. Located in nucleus. Is expressed in several structures, including central nervous system; early conceptus; gonad; sensory organ; and spleen. Orthologous to human SSB (small RNA binding exonuclease protection factor La). [provided by Alliance of Genome Resources, Nov 2024]

    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.

      Description
      Transcript Variant: This variant (3) differs in the 5' UTR and uses an alternate in-frame splice junction in the 3' end compared to variant 1. The resulting isoform (b) has the same N- and C-termini but is 1 aa shorter compared to isoform a. Variants 3, 8, and 9 all encode the same isoform (b).

    1. NR_149321.2 RNA Sequence

      Status: VALIDATED

      Description
      Transcript Variant: This variant (4) differs in the 5' UTR and lacks an alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
