• To discuss the link between ER structure and cellular function.
• To explore diseases associated with ER structural defects.

Main Methods:

• Literature review of recent studies on ER structure and dynamics.
• Analysis of research on ER-shaping proteins and their functions.
• Synthesis of findings on ER structure-related diseases.

Main Results:

• Key proteins and forces are identified as critical for ER shape maintenance.
• Novel ER domains and functions have been discovered.
• Mutations in ER-shaping proteins are linked to various diseases.

Conclusions:

• ER architecture is vital for its diverse cellular roles.
• Defects in ER structure can lead to significant health implications.
• Further research into ER dynamics and disease is warranted.
