| 背景 | CNN-1 (calponin-1 [calcium and calmodulin-binding troponin T-like protein]; also calponin basic, CaP and calponin H1) is a 32-36 kDa cytoplasmic member of the calponin family of proteins. Although reportedly expressed in fibroblasts and endothelial cells, it actually appears to be restricted to smooth muscle and smooth muscle-like cells such as myoepithalium and myofibroblasts in the adult. CNN-1 interacts with F-actin in a phosphorylation-dependent manner. When nonphosphorylated, CNN-1 blocks actomyosin ATPase activity, contributing to the stabilization of actin stress fiber bundles. Thus, CNN-1 expression inhibits cell motility and the formation of podosomes. Human CNN-1 is 297 amino acids (aa) in length. It contains one CH/calponin homology domain (aa 30-127), and three consecutive calponin-like repeats (aa 164-268). The repeats are suggested to mediate actin binding. There are five potential Ser/Thr phosphorylation sites. Full-length human CNN-1 shares 97% aa sequence identity with mouse CNN-1. |

Calponin 1 in MDA‑MB‑231 Human Cell Line. Calponin 1 was detected in immersion fixed MDA‑MB‑231 human breast cancer cell line using Sheep Anti-Human Calponin 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7900) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Calponin 1 in Human Small Intestine. Calponin 1 was detected in immersion fixed paraffin-embedded sections of human small intestine using Sheep Anti-Human Calponin 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7900) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to smooth muscle cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections. |
