Detection of Human Laforin/EPM2A by Western Blot. Western blot shows lysates of human heart and brain tissue, and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL Mouse Anti-Human Laforin/EPM2A Monoclonal Antibody (Catalog # MAB5714) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human Laforin (3 ng) was included. A specific band for Laforin/EPM2A was detected at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Laforin, also known as Lafora PTPase and EPM2A, is a 38 kDa member of the protein tyrosine phosphatase family. Human Laforin is 331 aa in length and contains one carbohydrate binding type-20 (CBM20) domain (aa 1-124) and one tyrosine-protein phosphatase domain (aa 243-311). Multiple splicing variants produce four isoforms of human Laforin, which is most highly expressed in heart, skeletal muscle, kidney, pancreas and brain. It functions as a dual specificity protein phosphatase and may be involved in the control of glycogen metabolism. Mutations in Laforin cause progressive myoclonic epilepsy type 2, also known as Lafora disease.
