| R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Ca2+/S100 proteins act as upstream regulators of the chaperone-associated ubiquitin ligase CHIP (C terminus of Hsc70-interacting protein). | |

| 背景 | S100A2 (also S100L and CaN19) is a 10 kDa member of the S100 family, EF-hand superfamily of Ca-binding proteins. It is expressed by multiple cell types including keratinocytes, chondrocytes, and bronchial epithelium. S100A2 regulates both Ca and Zn (in human) within cells and increases p53 activity. It forms both noncovalent and covalent homodimers and a homotetramer under certain conditions. Human S100A2 is 98 amino acids (aa) in length. It contains two EF-hand motifs (aa 13‑48 and 51‑86) plus a calcium (aa 64‑75) and zinc (aa 17‑22) binding site. There is one potential alternative splice form that shows a 40 aa insertion after Gly48. Full-length human S100A2 shares 89% and 85% aa identity with bovine and canine S100A2, respectively. |

Detection of Human S100A2 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Human S100A2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4870) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for S100A2 at approximately 8 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8. | |
S100A2 in MDA‑MB‑231 Human Cell Line. S100A2 was detected in immersion fixed MDA‑MB‑231 human breast cancer cell line using Goat Anti-Human S100A2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4870) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI(blue). Specific staining was localized to nucleus and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips. |
