Western blot - Anti-TRA-1-81 antibody [TRA-1-81] - Stem Cell Marker (AB16289)

This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab16289 overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP, and visualised using ECL development solution ab133406.

TRA-1-81 also known as podocalyxin-like protein 1 (PODXL) or Gp200 is a cell surface protein with a mass of approximately 140 kDa. It belongs to a group of proteins recognized by the SSEA-4 antibody. TRA-1-81 expresses significantly in embryonal carcinoma cells pluripotent stem cells and certain tumors and it has been identified on human embryonic stem cells. This protein acts as a marker for undifferentiated cells due to its presence on the surface playing a role in maintaining the pluripotent state.
Biological function summary

TRA-1-81 functions in maintaining cell pluripotency and influences cell adhesion properties. It does not form part of a larger protein complex but interacts closely with glycans present on the cell surface. These glycans are significant for the protein’s role in cell signaling and maintaining stemness. TRA-1-81's expression level often correlates with the ability of cells to self-renew and resist differentiation highlighting its role in early embryonic development.

Pathways

TRA-1-81 is involved in the regulation of signaling pathways that control cell pluripotency and differentiation notably the Wnt and Hedgehog pathways. These pathways facilitate communication within cells that decide cell fate proliferation and differentiation. TRA-1-81 has relation to other pluripotency-related proteins such as OCT4 and SOX2 through these biological pathways contributing to the complex regulation of stem cell maintenance and development.

TRA-1-81 is involved in various cancers specifically testicular and ovarian cancers. The abnormal expression of this protein indicates cancer stem cells which contribute to tumor growth and resistance to therapies. Additionally TRA-1-81 is connected to metastasis in these cancers parallel to its role in cell adhesion. Its relationship with proteins like E-cadherin in cancer pathways further shows how TRA-1-81 can impact disease progression and resistance mechanisms in tumor environments.
