Summary
The KCC2 transporter regulates neuronal inhibition by controlling chloride levels. This review discusses KCC2
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- KCC2 (SLC12A5) is a neuronal cation-chloride cotransporter critical for regulating intracellular chloride concentration.
- KCC2 plays a vital role in inhibitory neurotransmission mediated by GABA and glycine.
- Dysfunctional KCC2 cell surface transport is implicated in various neuropathological conditions.
Purpose of the Study:
- To review known mechanisms regulating KCC2 membrane trafficking.
- To discuss signals, pathways, and proteins involved in KCC2 functional surface expression.
Main Methods:
- Literature review of existing research on KCC2.
- Analysis of cellular mechanisms governing KCC2 trafficking and surface expression.
Main Results:
- KCC2 exhibits developmentally regulated expression, crucial for establishing neuronal inhibition.
- Functional surface expression of KCC2 is essential for its role in neurotransmission.
- Impairments in KCC2 trafficking can lead to neuropathology.
Conclusions:
- Understanding KCC2 membrane trafficking is key to addressing neurological disorders.
- Further research into KCC2 regulatory proteins and pathways is warranted.

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

Enzymes like flippase, floppase, and scramblase transfer phospholipids from one layer to another in the membrane, thereby affecting membrane asymmetry.
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...

18.3K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

01:26Transport Across the Golgi
6.3K
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
