Data for the Blood Proteoform Atlas:DS-65:T-cell CD4:Purchased from STC

ABSTRACT: Human biology is tightly linked to proteins, yet most measurements do not precisely determine their full sequence and post-translational modifications. Here, we present the primary structures of 30,000 unique proteoforms expressed from 1,690 human genes across 21 cell types and plasma from human blood and bone marrow compiled in the Blood Proteoform Atlas (BPA). Our results indicate that while a given protein can be expressed across multiple cell types, the proteoform functions as a more specific indicator of differentiation. These results provide a better biochemical description of protein-level biology expressed through gene transcription and translation. We demonstrate the utility of the BPA by focusing on cell- and proteoform-specific signatures within 58 liver transplant recipients having healthy graft function or undergoing acute organ rejection or dysfunction.
