pHi regulatory ion transporters: an update on structure, regulation and cell function

Area of Science:

• Cell Biology
• Physiology
• Biochemistry

Background:

• Intracellular pH (pHi) critically regulates essential cellular functions.
• Maintaining a stable pHi is crucial for normal cellular activity.
• Cells utilize plasma membrane ion transporters to manage intracellular H+ levels.

Purpose of the Study:

• To review the molecular identity of major membrane pH-regulatory ion transporters.
• To summarize the regulation of these transporters, including neurohormonal influences.
• To describe the functions of key ion transporters involved in pH homeostasis.

Main Methods:

• Literature review of scientific publications.
• Synthesis of information on molecular identity, regulation, and function.
• Focus on membrane-bound ion transport systems.

Main Results:

• Identified key ion transporters responsible for pHi regulation.
• Detailed the mechanisms of neurohormonal control over these transporters.
• Elucidated the functional roles of these transporters in cellular physiology.

Conclusions:

• Membrane ion transporters are essential for maintaining cellular pH homeostasis.
• These transporters are subject to complex regulation, including neurohormonal pathways.
• Understanding these transporters is key to understanding cellular function and dysfunction.
