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. NM_001099951.4 → NP_001093421.1  ciliary microtubule inner protein 2B isoform 2

    See identical proteins and their annotated locations for NP_001093421.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) uses an alternate splice junction at the 5' end of a coding exon compared to variant 1, that causes a frameshift. The resulting isoform (2) has a shorter and distinct C-terminus compared to isoform 1.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) has multiple differences in the coding region, one of which results in a translational frameshift, compared to variant 1. The resulting protein (isoform 3) has a distinct internal region and is shorter than isoform 1.
