Is osteocalcin a gene?
Osteocalcin, also known as bone gamma-carboxyglutamic acid-containing protein (BGLAP), is a small (49-amino-acid) noncollagenous protein hormone found in bone and dentin, first identified as a calcium-binding protein in chick bone….Osteocalcin.

What is the promoter section of a gene?
​Promoter. A promoter is a sequence of DNA needed to turn a gene on or off. The process of transcription is initiated at the promoter. Usually found near the beginning of a gene, the promoter has a binding site for the enzyme used to make a messenger RNA (mRNA) molecule.
Where is the promoter gene located?
Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5′ end of the transcription initiation site.
What increases osteocalcin?
Weight loss, exercise, and supplements such as vitamin K can help improve bone health and increase osteocalcin levels.
Where is osteocalcin produced?
In response to insulin, undercarboxylated osteocalcin is produced by the osteoblast or released from the bone matrix by the low pH of the osteoclast resorption pit and enters the circulation where it acts as a hormone.
How does promoter affect gene expression?
Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. Thus the promoter region controls when and where in the organism your gene of interest is expressed.
Does every gene have a promoter?
Every gene has a promoter, which is the binding site for the basal transcriptional apparatus – RNA polymerase and its co-factors. This provides the minimum machinery necessary to allow transcription of the gene.
What stimulates osteocalcin production?
Physical exercise can significantly increase the levels of osteocalcin. In Pernambuco et al. (2013) study, an 8-months aquatic aerobic exercise program is effective in increasing circulating osteocalcin levels in post-menopausal women with low bone mineral density (Pernambuco et al., 2013).
Can a company run without promoter?
SEBI regulations allow companies to have zero promoter holding according. The SEBI regulations require a minimum 25 per cent of public shareholding but there is no legal requirement of minimum promoter group holding.
