Summary
This study presents the largest human red blood cell (RBC) proteome dataset to date. It identifies over 5000 proteins, offering new insights into RBCs and related diseases.
Area of Science:
- Proteomics
- Cell Biology
- Biochemistry
Background:
- Red blood cells (RBCs) are vital for human health and implicated in numerous clinical disorders.
- Existing human RBC proteomics studies have limited coverage, hindering a complete understanding of RBC protein profiles and associated disease mechanisms.
Purpose of the Study:
- To perform an in-depth proteomic analysis of human RBCs using advanced mass spectrometry.
- To identify a comprehensive set of proteins in RBC membrane and cytoplasmic fractions.
- To establish a valuable data resource for understanding RBCs and their related diseases.
Main Methods:
- Human RBCs were isolated and separated into membrane and cytoplasmic fractions.
- Extensive offline basic pH RPLC fractionation was employed.
- Proteomic analyses were conducted using advanced mass spectrometry techniques.
Main Results:
- Identified 4777 proteins in the RBC membrane fraction.
- Identified 2350 proteins in the RBC cytoplasmic fraction.
- Achieved a total of 5264 identified proteins, representing a large-scale human RBC proteome analysis.
Conclusions:
- The comprehensive RBC proteome dataset significantly expands the known human RBC protein landscape.
- This resource is crucial for elucidating the roles of RBCs in health and disease.
- The findings pave the way for deeper investigations into RBC-related pathologies.

90.3K
The cytoplasm consists of organelles and a framework of protein scaffolds called the cytoskeleton suspended in an aqueous solution, the cytosol. The cytosol is a rich broth of water, ions, salts, and various organic molecules.
Protein Folding and Misfolding
The cytoplasm is the location for several cellular processes, including protein synthesis and folding. The aqueous nature of the cytosol promotes protein folding such that the hydrophobic amino acid side chains are buried in the protein...

9.8K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

02:33Distribution of Cytoplasmic Content
4.7K
Cytokinesis segregates a cell’s chromosomes and organelles into its daughter cells. Organelles divide and grow prior to cell division but cannot be synthesized de novo; therefore, cells must receive at least one copy of each organelle to survive. Currently, many of the details of how the organelles are distributed are not yet fully elucidated.

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

01:16Introduction to Membrane Proteins
81.4K
The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...
