Summary: This gene encodes a stromal cell derived factor that is a member of the CREC protein family. The encoded protein contains six EF-hand motifs and calcium-binding motifs. This protein localizes to the Golgi lumen and may be involved in regulating calcium dependent cellular activities. [provided by RefSeq, Sep 2011]

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.

NM_016176.6 → NP_057260.3 45 kDa calcium-binding protein isoform 2 precursor

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses a different splice site in the 3' coding region, compared to variant 1, that results in a frameshift. It encodes isoform 2, which has a shorter and distinct C-terminus compared to isoform 1.
