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_001303105.2 → NP_001290034.1  coiled-coil domain-containing protein 138 isoform 2

    See identical proteins and their annotated locations for NP_001290034.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) lacks an exon in the 3' coding region, which results in a frameshift compared to variant 1. The encoded isoform (2) has a shorter and distinct C-terminus compared to isoform 1.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) uses an alternate splice site in its 5' UTR which results in the use of a downstream in-frame start codon, compared to variant 1. The encoded isoform (3) has a shorter N-terminus, compared to variant 1. Variants 3 and 16 both encode the same isoform (3).
