The rapid development of high accuracy and high sensitivity mass spectrometry technologies has revolutionized our understanding of proteins and their contribution to cellular function. However, there is an increasingly apparent disconnect between these state-of-the-art tools and their effective applications to advance cardiovascular biology and medicine. Despite progress made in certain areas of investigation, cardiovascular proteomic research faces three major challenges: the excessive cost of instrumentation; the limited accessibility of advanced proteomic technology to the cardiovascular community at large; and the overwhelming quantity and fragmented nature of mass spectra datasets lacking functional annotations. These economic, technological, and informatic limitations are prohibitive to further advancement of the field.

To move the field forward, our investigator team identified several key challenges that commonly surround mass spectrometer data processing and non-targeted database searches. Accordingly, we propose the construction of a Cardiac-specific Organellar Peptide Spectral (COPa) Library, which will provide a specialized, comprehensive, and interactive resource for the cardiovascular community. We aim to engineer a robust and high fidelity library to enable targeted peptide data searches with functional annotations. This library will catalogue experimental peptide spectra obtained from cardiovascular organelles of various species; it will contain a Wiki-like web interface to engage the participation of the cardiovascular community; and it will build a cardiovascular proteome knowledgebase with efforts from proteomic scientists, biologists, and cardiovascular clinicians.

In summary, this COPa Library will create an essential tool box to support the translation of proteomic data into the advancement of cardiovascular biology and medicine; it will bridge the gap between traditional data-driven proteomic studies and hypothesis-driven investigations widely employed by the cardiovascular community, propelling innovation and new discoveries.
