Abstract:
An extensive catalog of plasma membrane (PM) protein mutations related to phenotypic diseases is associated with incorrect protein folding and/or localization. These impairments, in addition to dysfunction, frequently promote protein aggregation, which can be detrimental to cells. Here, we review PM protein processing, from protein synthesis in the endoplasmic reticulum to delivery to the PM, stressing the main repercussions of processing failures and their physiological consequences in pathologies, and we summarize the recent proposed therapeutic strategies to rescue misassembled proteins through different types of chaperones and/or small molecule drugs that safeguard protein quality control and regulate proteostasis.
Insights
Plasma membrane (PM) protein mutations cause disease through misfolding and aggregation. This review covers PM protein processing, its failures, and therapeutic strategies using chaperones and drugs to restore proteostasis.
Area of Science:
- Cell Biology
- Molecular Biology
- Pathology
Background:
- Mutations in plasma membrane (PM) proteins are linked to various diseases.
- These mutations often lead to incorrect protein folding and localization, causing cellular dysfunction.
- Protein aggregation resulting from these defects can be toxic to cells.
Purpose of the Study:
- To review the processing of PM proteins from synthesis to delivery.
- To highlight the consequences of PM protein processing failures in disease.
- To summarize current therapeutic strategies for correcting misassembled PM proteins.
Main Methods:
- Review of scientific literature on PM protein processing and related diseases.
- Analysis of the impact of protein folding and localization defects.
- Summary of therapeutic approaches involving chaperones and small molecule drugs.
Main Results:
- PM protein processing involves synthesis, folding, and transport.
