NCBI Reference Sequences (RefSeq)

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_001195731.2NP_001182660.2  chondroitin sulfate synthase 2 isoform 2

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) contains an alternate 5' terminal exon compared to variant 1, resulting in translation initiation from an in-frame downstream AUG, and an isoform (2) with a shorter N-terminus compared to isoform 1.
