Recombinant Human CA4, GST-tagged

• Cat.No.: CA4-10621H
• Product Overview: Recombinant Human CA4 protein, fused to GST-tag, was expressed in E.coli and purified by GSH-sepharose.

Specification

• Description: Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. This gene encodes a glycosylphosphatidyl-inositol-anchored membrane isozyme expressed on the luminal surfaces of pulmonary (and certain other) capillaries and proximal renal tubules. Its exact function is not known; however, it may have a role in inherited renal abnormalities of bicarbonate transport.

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.
