Biological background
The proton-activated Cl- (PAC) channel, which opens by extracellular acidic pH, has been well characterized in several cells and tissues by electrophysiology recordings, although its molecular identity was unknown.Recently, two independent groups, identified a two-transmembrane protein named PACC1 (or TMEM206) as the molecular underlie of the proton-activated Cl- channel 1,2.PACC1 has no discernible sequence homology with previously characterized Cl- channels, although its structure of two transmembrane domains with cytoplasmic N- and C-termini and a large extracellular loop, resembles that of the Na+ -selective channels ASICs and ENaCs. In fact, recent work suggests that the functional unit of the proton-activated Cl- channel is a trimeric form of PACC1 subunits3,4.PAC activity that is stimulated by the lowering of extracellular pH and has been recorded in a wide range of mammalian cells and tissues. Acidic pH is crucial for the function of intracellular organelles in the secretory and endocytic pathways and is also one of the pathological hallmarks of many diseases, including cerebral and cardiac ischemia, cancer, infection and inflammation.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-CL031.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
