Summary: A structural constituent of bone. Involved in several processes, including cellular response to vitamin D; cellular response to zinc ion starvation; and response to hydroxyisoflavone. Located in several cellular components, including dendrite; extracellular space; and perikaryon. Used to study congenital hypothyroidism and osteoporosis. Biomarker of autosomal dominant hypocalcemia; end stage renal disease; osteoporosis; polycystic kidney disease; and type 1 diabetes mellitus. Human ortholog(s) of this gene implicated in osteoarthritis; osteoporosis; prostate cancer; rheumatoid arthritis; and vitamin K deficiency bleeding. Orthologous to human BGLAP (bone gamma-carboxyglutamate protein). [provided by Alliance of Genome Resources, Jun 2025]
Expression: Biased expression in Thymus (RPKM 5.0), Spleen (RPKM 2.9) and 9 other tissues See more

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.
