This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Pituitary-specific positive 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 Pituitary-specific positive 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 Pituitary-specific positive 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:
Pituitary-specific positive transcription factor 1, also known as Growth hormone factor 1, plays a pivotal role in the development of the anterior pituitary gland. It specifically binds to the consensus sequence 5'-TAAAT-3', activating growth hormone and prolactin genes. This transcription factor is crucial for the specification of lactotrope, somatotrope, and thyrotrope phenotypes, essential for normal pituitary function.
Therapeutic significance:
The protein is linked to Combined Pituitary Hormone Deficiency (CPHD1), characterized by growth hormone, prolactin, and thyroid-stimulating hormone deficiencies. Understanding the role of Pituitary-specific positive transcription factor 1 could open doors to potential therapeutic strategies for treating CPHD1, offering hope for patients suffering from severe growth deficiency and intellectual disability.
