Results of validation by standard or enhanced validation.
Standard validation is based on concordance with available experimental gene/protein characterization data in the UniProtKB/Swiss-Prot database. Standard validation results in scores Supported, Approved or Uncertain.
Enhanced validation is performed using either siRNA knockdown, tagged GFP cell lines or independent antibodies. For the siRNA validation the decrease in antibody-based staining intensity upon target protein downregulation is evaluated. For the GFP validation the signal overlap between the antibody staining and the GFP-tagged protein is evaluated. For the independent antibodies validation the evaluation is based on comparison of the staining of two (or more) independent antibodies directed towards independent epitopes on the protein.
For all cases except the siRNA validation, an image representative of the antibody staining pattern is shown. For the siRNA validation, a box plot of the results is shown.
The subcellular location is not consistent with literature.
Immunofluorescent staining of human cell line U-251 MG shows localization to plasma membrane & cytosol.

A Western blot analysis is performed on a panel of human tissues and cell lines to evaluate antibody specificity. For antibodies with unreliable result a revalidation using an over-expression lysate is performed.
Western Blot is used for quality control of the polyclonal antibodies generated in the project. After purification, the antibodies are used to detect bands in a setup of lysate and different tissues. The result is then scored Enhanced, Supported, Approved, or Uncertain.
Enhanced validation includes five different methods: Genetic validation, Recombinant expression validation, Independent antibody validation, Orthogonal validation and Capture MS validation.
