A new study by an international team of researchers from the University of Barcelona and the University of Montpelier has enabled them to determine the role of a disordered region, Called ULBR, of the Src protein in the regulation of this protein\u2019s oncogenic capacity. The ULBR region has been found by the Biomolecular NMR Research Group (BIO-RMN<\/a>) located at the Barcelona Science Park, thanks to the tools provided by the nuclear magnetic resonance (NMR), a technique in which the UB is at the forefront.<\/b><\/p>\n

The Src protein takes part in the regulation of many physiological processes such as the survival, migration or cell adhesion as a response to stimuli received from several receptors of the membrane. Although it is demonstrated that its deregulation is involved in the proliferation of cancer in humans, many aspects of this function are still unknown, especially regarding its disordered region.<\/p>\n

Now, a study published in the journal Oncogene shows that mutations of the disordered region, called ULBR, inhibit by more than 50% the transforming activity of this protein in colon cancer cells and the growth of Src-dependent tumours in mice.<\/p>\n

The ULBR region has been found by the Biomolecular NMR Research Group (BIO-RMN<\/a>) at the Barcelona Science Park\u00a0thanks to the tools provided by the nuclear magnetic resonance (NMR), a technique in which the UB is at the forefront. The study was carried out with researchers from the University of Montpellier (France), experts on colorectal cancer, thanks to a collaboration that started with a project of La Marat\u00f3 de TV3 on cancer.<\/p>\n

\u201cThis study reveals the relevant role of this intrinsically disordered region in the malignant cell transformation and it suggests a novel layer of Src regulation by this unique region\u201d, says Miquel Pons,<\/strong> professor at the Department of Inorganic and Organic Chemistry and director of the BIO-RMN group.<\/p>\n

Most eukaryotic proteins have intrinsically disordered regions (IDR) that challenge the classical structure-function paradigm. Therefore, the classical strategies based on the determination of structures or inactivation of whole domains had made it impossible for researchers to find the regulating role of the Src disordered region, probably because \u201cit may contain opposite regulatory sequences\u201d, as Dr. Pons notes.<\/p>\n

Following this idea, the team inactivated specifically a small region within the disordered domain that showed a unique response by NMR, showing its essential role in the tumoral activity of the protein.<\/p>\n

The use of NMR for the study of disordered proteins has become a strategical option for the UB, which obtained nearly nine million euros in funding for the installation of a state-of-the-art equipment in the PCB, to be the most powerful in Spain.<\/p>\n
