Scientific Data Images for Human PTPN14 Antibody
Detection of Human PTPN14 by Western Blot.
Western blot shows lysates of DU145 human prostate carcinoma cell line, HT-29 human colon adenocarcinoma cell line, and HT-29 human colon adenocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Human PTPN14 Monoclonal Antibody (Catalog # MAB4458) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PTPN14 at approximately 135 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
PTPN14 in Human Placenta.
PTPN14 was detected in immersion fixed paraffin-embedded sections of human placenta using Human PTPN14 Monoclonal Antibody (Catalog # MAB4458) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Background: PTPN14
Protein Tyrosine Phosphatase, Non-receptor type 14 (PTPN14), also called Phosphatase with Ezrin Domain (PEZ) and PTP36, is a 135 kDa cytosolic protein that dephosphorylates tyrosine residues in proteins. PTPN14’s Ezrin domain is homologous to erythrocyte Band 4.1 protein, targeting the phosphatase to cytoskeletal elements such as actin. PTPN14 associates with beta-catenin in adhesion zones in cells that are touching, but is nuclear in isolated, proliferating cells. Loss-of-function mutations in PTPN14 are found in 26% of colorectal cancers, suggesting it is a tumor suppressor.
