Definition

Noun: The complete set of proteins that can be expressed or is expressed by a cell, tissue, or organism at a given time under defined conditions. It is the protein counterpart to the genome.

Usage

The term "proteome" is used in the fields of molecular biology, biochemistry, and systems biology to describe the entire protein profile. It refers to a dynamic set that can change in response to environmental factors, developmental stage, or disease state, unlike the static genome.

Examples

• Noun:
  • Studying the proteome of a cancer cell can reveal potential targets for new drugs.
  • The human proteome is vastly more complex than the human genome due to mechanisms like alternative splicing and post-translational modifications.
  • Researchers compared the proteome of healthy tissue with that of the infected tissue to identify biomarkers.

Advanced Usage

• "Proteome-wide": Referring to an analysis or study that encompasses the entire proteome.
  • The team conducted a proteome-wide screen for protein-protein interactions.
• "Proteome dynamics": The study of how the proteome changes over time or under different conditions.
  • Her research focuses on proteome dynamics during cellular stress.

Variants and Related Words

• Proteomics (n): The large-scale study of proteomes, their structures, and functions.
  • Advances in proteomics have accelerated biomarker discovery.
• Proteomic (adj): Relating to proteomics or the proteome.
  • They used a proteomic approach to analyze the samples.

Synonyms

• Protein complement: A less common synonym emphasizing the full set of proteins.
• Protein profile: Often used when referring to the set of proteins expressed in a specific sample or condition.

Related Phrases and Concepts

• "Map the proteome": To identify and catalog all the proteins expressed.
  • An international project aims to map the human proteome.
• "Proteome complexity": Refers to the intricate and variable nature of the proteome compared to the genome.
  • Alternative splicing contributes significantly to proteome complexity.

Noun

1. the full complement of proteins produced by a particular genome
