CAPG (capping protein, gelsolin-like) is an actin-binding protein, which is expressed ubiquitously. It belongs to the Ca2+- and polyphosphoinositide-regulated villin/gelsolin superfamily, and caps the barbed end of the growing actin microfilament.
Recombinant capping protein (actin filament), gelsolin-like
Application
Anti-CAPG antibody produced in chicken is suitable for western blotting analysis at a dilution of 1:500, for tissue or cell staining at a dilution of 1:200.
Biochem/physiol Actions
Macrophage-capping protein (CAPG) plays a critical role in regulating the migration ability of cells. It is a Ca2+-sensitive protein, which reversibly blocks the barbed ends of actin filaments, but does not sever preformed actin filaments. CAPG helps in promoting tumor cell invasion, but not cell proliferation. It is involved in the process of metastasis by promoting the invasiveness of tumor cells. It can act as a biomarker in risk-stratification therapy for gastric cancer and as a therapeutic target in Hepatocellular carcinoma (HCC). CAPG is also identified as a novel candidate biomarker to predict response to gemcitabine treatment and survival in cholangiocarcinoma as well as lung adenocarcinoma.
Physical form

Macrophage capping protein (MCP) is a Ca(2+)-sensitive protein which reversibly blocks the barbed ends of actin filaments but does not sever preformed actin filaments. The human cDNA for MCP has been cloned and sequenced. The derived amino acid sequence predicts

To reveal the proteomic background of lymph node metastasis (LNM) in gastric cancer, we performed a proteomic study of tumor and matched nontumor tissues obtained from surgically resected specimens of 22 patients with or without LNM. Using laser microdissection, we

Cholangiocarcinoma is one of the deadliest malignancies worldwide. Recent studies reported that treatment with gemcitabine was effective in prolonging survival. However, as the treatment only benefited a limited subset of patients, selection of patients before treatment is required. To discover
Hepatocellular carcinoma (HCC) is one of the most deadly cancers worldwide. We performed a proteomic study to understand the molecular mechanisms underlying metastasis in HCC. Among the 3491 protein spots observed by two-dimensional difference gel electrophoresis (2D-DIGE), we found that
