Available from Reaxense
This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Nucleolar transcription factor 1 including:
1. LLM-powered literature research
Our custom-tailored LLM extracted and formalized all relevant information about the protein from a large set of structured and unstructured data sources and stored it in the form of a Knowledge Graph. This comprehensive analysis allowed us to gain insight into Nucleolar transcription factor 1 therapeutic significance, existing small molecule ligands, relevant off-targets, and protein-protein interactions.

2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of Nucleolar transcription factor 1, including large-scale conformational changes along "soft" collective coordinates. Through molecular simulations with AI-enhanced sampling and trajectory clustering, we explored the broad conformational space of the protein and identified its representative structures. Utilizing diffusion-based AI models and active learning AutoML, we generated a statistically robust ensemble of equilibrium protein conformations that capture the receptor's full dynamic behavior, providing a robust foundation for accurate structure-based drug design.

3. Binding pockets identification and characterization
We employed the AI-based pocket prediction module to discover orthosteric, allosteric, hidden, and cryptic binding pockets on the protein’s surface. Our technique integrates the LLM-driven literature search and structure-aware ensemble-based pocket detection algorithm that utilizes previously established protein dynamics. Tentative pockets are then subject to AI scoring and ranking with simultaneous detection of false positives. In the final step, the AI model assesses the druggability of each pocket enabling a comprehensive selection of the most promising pockets for further targeting.

Background:
Nucleolar transcription factor 1, also known as Upstream-binding factor 1 and Autoantigen NOR-90, plays a pivotal role in ribosomal RNA gene transcription. It activates transcription mediated by RNA polymerase I by interacting with the SL1/TIF-IB complex and binds specifically to the upstream control element. This protein's function is crucial for the proper synthesis of ribosomal RNA, a fundamental process for cellular growth and proliferation.
Therapeutic significance:
Nucleolar transcription factor 1 is linked to Neurodegeneration, childhood-onset, with brain atrophy, a devastating condition characterized by progressive cortical atrophy, developmental delay, and loss of motor skills. Understanding the role of Nucleolar transcription factor 1 could open doors to potential therapeutic strategies for this neurodegenerative disease, offering hope for targeted interventions.
