Full Form of PXD

What is PXD?

PXD stands for ProteomeXchange Dataset, a unique identifier assigned to datasets submitted to the ProteomeXchange consortium, an international framework for sharing proteomics data. In India, PXD identifiers are widely used by researchers in institutions such as the Indian Institute of Science (IISc), the Indian Institutes of Technology (IITs), and the National Centre for Biological Sciences (NCBS) to deposit mass spectrometry-based proteomics data. These datasets underpin studies on protein expression, post-translational modifications, and biomarker discovery. The PXD system ensures that data is findable, accessible, interoperable, and reusable (FAIR), following global standards adopted by journals like Nature and Cell. In the Indian context, PXD references appear in research papers, thesis documents, and grant reports to link raw data publicly. For students pursuing postgraduate degrees in bioinformatics, molecular biology, or biotechnology, understanding PXD is essential for data submission and retrieval from repositories such as PRIDE Archive. The identifier is also relevant for competitive exams like CSIR-UGC NET, GATE, and ICMR-JRF, where questions on data repositories and bioinformatics tools are common. By using PXD, Indian research gains international visibility and reproducibility, fostering collaborations in the global proteomics community.
