🔬 𝑵𝒆𝒘! 𝐑𝐀𝐒 𝐬𝐢𝐠𝐧𝐚𝐥𝐥𝐢𝐧𝐠 𝐜𝐨𝐦𝐩𝐥𝐞𝐱𝐞𝐬 𝐢𝐧 𝐭𝐡𝐞 𝐂𝐨𝐦𝐩𝐥𝐞𝐱 𝐏𝐨𝐫𝐭𝐚𝐥 RAS proteins function in multi-protein assemblies that drive MAPK & PI3K signalling.
Now curated:
• SHOC2-MRAS-PP1 phosphatase complexes (RAF activation; linked to RASopathies incl. Noonan-like syndromes)
• KRAS/HRAS-SOS1 activation complexes
• KRAS-RAF1 & KRAS/MRAS-PIK3CA effector complexes
🧬 Oncogenic KRAS mutations (pancreatic, colorectal, lung cancers) stabilize these complexes, sustaining growth signalling. Explore RAS at the complex level → new therapeutic insights. #RAS #KRAS #RASopathies #CancerBiology #ComplexPortal
🌍 Rare Disease Day: When Molecular Complexes Break
Rare diseases aren’t just “gene disorders” - many disrupt macromolecular complexes, the molecular machines that keep cells running.
🔬 Dynein complex variants (e.g. DYNC1H1) impair axonal transport → Charcot-Marie-Tooth disease (CMT).
🔥 STING gain-of-function variants hyperactivate interferon signalling → SAVI.
Integrating resources like Complex Portal, MONDO, OMIM & EFO helps map diseases to complexes - a powerful lens for research and clinical insight.

From a farm in the north of England to the frontiers of bioinformatics, our Group Leader Sandra Orchard reflects on a career building the data foundations of modern biology:
“AI is showing how vital data curation really is.”
