Mouse Anti-Human Carbonic Anhydrase XII Monoclonal Antibody

• Cat.No.: CAB11484MH
• Product Overview: Mouse monoclonal antibody to human carbonic anhydrase XII.

Specification

• Antigen Description: Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes first discovered in 1933 that catalyze the reversible hydration of carbon dioxide. CAs 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. CA12, also known as Car12 and carbonic anhydrase XII, is a type I membrane enzyme highly expressed in colon, kidney, prostate, intestine and activated lymphocytes and moderately expressed in pancreas, ovary, and testis. This bitopic membrane protein contains an N-terminal extracellular catalytic domain, a membrane-spanning α-helix, and a small intracellular C-terminal domain. Two alternatively spliced forms exist, which either contains or lacks a 11 amino acid segment just before the transmembrane domain. The structure reveals a prototypical CA fold and two CA XII domains associate to form an isologous dimer. Overexpression of the CA12 is observed in certain human cancers and is used as a tumor marker.

Q&As

Are there any known inhibitors specific to CA12, and how do they impact its enzymatic function?

Known inhibitors can be identified through drug screening assays, and their impact on CA12 can be studied using kinetic studies and cell-based assays.

In which specific cellular compartments is CA12 predominantly localized, and how does this localization influence its role?

Cellular localization can be identified using immunofluorescence, subcellular fractionation, or electron microscopy.

What role does CA12 play in tumorigenesis, especially in hypoxic tumor environments?

CA12 has been implicated in tumor progression, particularly in hypoxic environments, by modulating pH and thus influencing tumor cell survival and metastasis. This can be assessed using cellular assays and tumor models.

What downstream signaling pathways are activated or inhibited by CA12?

Downstream pathways can be identified using pathway analysis tools, phosphoproteomics, and specific signal transduction assays.

How does CA12 activity get modulated under varying pH conditions?

The activity modulation under different pH conditions can be determined using enzymatic assays and pH shift experiments.

How does CA12 expression vary in response to different cellular stressors or stimuli?

Expression changes in response to stressors can be analyzed using techniques like qPCR, Western blotting, or proteomics following cellular treatment with specific agents.

How do genetic variants of the CA12 gene influence its protein structure and function?

Genetic variants and their impact can be determined using structural models and functional assays comparing wild-type and mutant proteins.
