Supplementary information

Stanniocalcin 2 (STC-2) is a glycoprotein hormone known for regulating calcium and phosphate homeostasis. It has other names like STC-1-related protein and STC2. The protein has a mass of approximately 33 kDa. STC-2 expresses in various tissues with high levels in the liver kidney and thyroid gland. Its expression suggests an important role in maintaining mineral balance in these tissues.
Biological function summary

STC-2 influences metabolic and inflammatory processes by modulating cellular responses to calcium and phosphate. It operates partly by binding to receptors on cell surfaces impacting cell proliferation and survival. While not part of a known complex STC-2 interacts with signaling molecules involved in bone metabolism and endocrine function serving as a modulator of mineralized tissue homeostasis.

Pathways

In mineral homeostasis STC-2 interacts within pathways involving calcium and phosphate regulation. Its interactions include overlap with the PTH (parathyroid hormone) and vitamin D pathways each critical for calcium and bone metabolism. STC-2 shows connections with proteins like FGF23 (fibroblast growth factor 23) that also participate in these regulatory networks impacting how cells manage mineral concentrations.

Research indicates STC-2's involvement in conditions such as chronic kidney disease and some cancers. Its expression levels correlate with abnormal mineral metabolism in kidney disease where it may interact with proteins like Klotho a known regulator of phosphate transport. In oncology overexpression of STC-2 associates with cancer progression potentially linking to altered signaling pathways in tumor cells.
