1075-Genetic Architecture of Murine Red Blood Cell Proteome
This study explores the genetic architecture of red blood cell (RBC) proteomes by analyzing fresh and stored blood from 350 diverse mice. The researchers identified over 6,000 quantitative trait loci, discovering that RBCs are primarily governed by trans-regulatory genetic variation due to their lack of new protein synthesis. Key hotspots at the Hba, Hbb, and Mon1a loci regulate essential functions, linking hemoglobin variation to oxidative stress and protein degradation. Notably, a specific cysteine residue (C93) in hemoglobin was identified as a critical regulator of redox balance and…
