Visual Proteomics
Visual proteomics represents a rapidly evolving interdisciplinary domain at the intersection of proteomics and vision science. It is dedicated to systematically elucidating the composition, function, regulatory mechanisms, and dynamic modulation of proteins in the visual system. As one of the most intricate and refined sensory systems in humans, vision depends on the coordinated activity of thousands of proteins across processes such as phototransduction, signal relay, energy metabolism, cellular maintenance, and immune surveillance. Given the inherent limitations of traditional molecular biology in capturing the complex spatial and temporal orchestration of these proteins, visual proteomics has emerged to fill this gap. Leveraging high-throughput mass spectrometry (MS) and advanced bioinformatics, this approach enables comprehensive identification and quantification of proteins in vision-related tissues—such as the retina, optic nerve, and choroid—thereby providing critical molecular insights into visual function. By constructing proteomic landscapes under physiological and pathological conditions, visual proteomics enables detection of fine-scale alterations in protein expression and post-translational modifications (PTMs). For instance, comparative proteomic profiling of retinas across developmental stages or during aging facilitates a deeper understanding of the molecular trajectories underlying visual maturation and decline. Additionally, this field places strong emphasis on deciphering protein-protein interaction (PPI) networks, highlighting the roles of key regulators, signaling pathways, and organelle-specific protein distributions. The multidimensional and integrative nature of visual proteomics makes it an indispensable tool for unraveling the regulatory architecture of vision and broadens the scope of visual biology.
Methodologically, visual proteomics combines classical MS platforms and rigorous sample preparation protocols with next-generation approaches such as spatially resolved proteomics and single-cell proteomics. The integration of MS imaging technologies further enhances the spatial resolution of proteome mapping, allowing localization of protein expression patterns at cellular and even subcellular levels. These innovations have laid a robust foundation for building high-resolution proteomic atlases of the visual system.
Sample diversity is another hallmark of visual proteomics. Both human ocular tissues and model organisms—including mice, pigs, and non-human primates—are extensively utilized to enable longitudinal studies. The genetic manipulability and experimental tractability of animal models facilitate investigations into developmental proteomic shifts, gene knockout effects, and proteomic responses to pharmacological or environmental perturbations. This systems biology–oriented framework empowers researchers to detect nuanced yet biologically critical variations in protein dynamics, thereby supporting mechanism-driven investigations.
The advancement of visual proteomics is tightly coupled with computational innovations. Large-scale MS datasets require sophisticated bioinformatics pipelines, encompassing database searching, statistical modeling, and functional annotation to filter noise and highlight significant trends. Recently, artificial intelligence (AI) and deep learning techniques have been incorporated to predict protein function, infer subcellular localization, and identify disease-associated proteomic signatures. Although still under refinement, the synergy between computational algorithms and experimental data is anticipated to propel visual proteomics toward even greater throughput, resolution, and precision.
