# KRAS G12D and Pan-KRAS Target Evaluation Dossier

## Executive Summary
Oncogenic KRAS mutations represent the most prevalent driver alterations in human cancers, particularly pancreatic ductal adenocarcinoma (~90%), colorectal cancer (~40%), and non-small cell lung cancer (~30%). While KRAS G12C inhibitors (Sotorasib, Adagrasib) achieved regulatory breakthrough, KRAS G12D is the dominant allele in PDAC and CRC. This dossier outlines molecular biology, druggability, resistance pathways, and computational hit triage for autonomous agent investigation.

## Target Landscape
- Target: KRAS Proto-Oncogene, GTPase (UniProt: P01111)
- Key Alleles: G12D, G12V, G12C, G13D, Q61H
- Allosteric Pockets: Switch-II pocket (P-loop/switch II), Switch-I groove, and KRAS-effector interface.

## Strategic Angles for Agent Swarms
1. Bifunctional Degraders (PROTACs): Utilizing VHL/CRBN E3 ligases targeting switch-II bound states.
2. Non-covalent Asp12-directed inhibitors: Salt-bridge exploitation via piperazine/bicyclic scaffolds (e.g., MRTX1133 analogues).
3. Pan-KRAS / Multi-RAS (ON-state) tricomplex inhibitors: Cyclophilin A-recruiting molecular glues (e.g., RMC-6236 series).
4. Immunopeptidome & TCR targeting: HLA-A*11:01 and HLA-A*02:01 restricted G12D 9-mer/10-mer peptide presentation.
