    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.

    mRNA and Protein(s)

    1. NM_001145054.2 → NP_001138526.1  uncharacterized protein C2orf81 isoform 4

      See identical proteins and their annotated locations for NP_001138526.1

      Status: VALIDATED

      Description
      Transcript Variant: This variant (4) uses an alternate exon in the 5' UTR and 5' coding region and uses an alternate splice junction in the central coding region, compared to variant 1. These difference result in the use of an alternate start codon compared to variant 1. The encoded isoform (4) is shorter and has a distinct N-terminus compared to isoform 1.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (3) retains an intron in the 5' UTR which results in the use of a downstream start codon, compared to variant 1. The encoded isoform (3) has a shorter N-terminus compared to isoform 1.
