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)

NM_001143682.2 → NP_001137154.1 calcium-binding and coiled-coil domain-containing protein 1 isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) omits an inframe coding exon and uses an alternate (in-frame) splice acceptor site, compared to variant 2. This results in a shorter protein (isoform 2).
