| Description | Podoplanin, also known as glycoprotein 36 (gp36), PA2.26 antigen, T1alpha (T1A), and aggrus, is a 36 kDa type I transmembrane sialoglycoprotein and member of the Podoplanin family. Podoplanin has three potential splice variants, the longest of which is represented by a 238 amino acid (aa) precursor (NP_006465). It contains an undefined signal sequence, a 22 aa transmembrane segment (aa 207-228) and a short cytoplasmic tail (aa 229-238). The ECD contains abundant Ser/Thr residues that could serve as potential Olinked glycosolation sites. The cytoplasmic tail contains putative sites for protein kinase C phosphorylation. There are two potential alternate start sites at Met 77 (Swiss Prot #: Q86YL7) and Met 119 (EAW51692) that generate short forms. The 162 aa short form Podoplanin precursor shares 47% aa identity with mouse Podoplanin. Podoplanin is expressed on glomerular epithelial cells (podocytes), type I lung alveolar cells, lymphatic endothelial cells, and numerous tumors, including colorectal tumors, squamous cell carcinomas, testicular seminoma, and brain tumors. One study shows high expression of Podoplanin mRNA in placenta, lung, skeletal muscle, and heart, and weaker levels in brain, kidney, and liver (1). Podoplanin is the ligand for Ctype lectin-like receptor 2 (CLEC2). Their association is dependent on sialic acid on Oglycans of Podoplanin. Through its association with CLEC2, Podoplanin induces platelet aggregation and tumor metastasis. Podoplanin is also necessary for lymphatic vessel formation, normal lung cell proliferation and alveolus formation at birth. |

Western Blot analysis of recombinant human [Cat# S01-046], mouse [Cat# S01-M46] and rat [Cat# S01-R46] soluble Podoplanin using a rabbit polyclonal anti-human Podoplanin antibody [Cat# 102-PA40AG]. There is a weak cross reactivity with mouse and rat Podoplanin visible.
Functional ELISA with anti-human Podoplanin [Cat# 102-PA40AG]. Recombinant human soluble Podoplanin [Cat# S01-046] was coated with increasing amounts in a 96 well microtiter plate.
Western Blot analysis of Podoplanin expression in human lymphatic endothelial cells (LEC) and HUVECs. Total lysate of both cell types were subjected to SDS-PAGE and subsequent Western analysis with the polyclonal (#102-PA40) antibody. The antibody recognizes a protein of about 36 kDa in total lysate from LECs but not from HUVEC.
