AI-ACCELERATED DRUG DISCOVERY
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 Nuclear factor 1 B-type 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 Nuclear factor 1 B-type 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 Nuclear factor 1 B-type, 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:
Nuclear factor 1 B-type, also known as CCAAT-box-binding transcription factor or TGGCA-binding protein, plays a pivotal role in brain development. It acts as a transcriptional activator of GFAP, recognizing and binding specific palindromic sequences in promoters and replication origins. This protein's activity is crucial for the transcription and replication processes in both viral and cellular contexts.
Therapeutic significance:
The protein is linked to Macrocephaly, acquired, with impaired intellectual development, a disorder marked by postnatal macrocephaly and varying degrees of neurodevelopmental issues. Understanding the role of Nuclear factor 1 B-type could open doors to potential therapeutic strategies for this and related neurodevelopmental disorders.
