Q&As

What role does CA4 play in the respiratory system?

CA4 assists in CO2 and bicarbonate regulation, pivotal for efficient respiratory gas exchange.

Which tissues or cell types predominantly express CA4?

CA4 is highly expressed in the kidney and red blood cells.

What is the primary physiological function of CA4?

CA4 catalyzes the reversible hydration of carbon dioxide, helping regulate pH and CO2 transport.

What are the known post-translational modifications on CA4?

Typical modifications like phosphorylation can be identified using techniques such as mass spectrometry.

Is CA4 implicated in any specific cellular signaling pathways?

While primarily enzymatic, any signaling roles for CA4 would require deeper investigation.

Are there known diseases or conditions associated with CA4 mutations or dysregulation?

CA4 dysregulation could relate to renal disorders or hematological abnormalities, though research is ongoing.

How does the enzymatic activity of CA4 compare to other carbonic anhydrase family members?

CA4, like other isoforms, is involved in CO2 hydration, but its specific efficiency and affinity might vary.
