Summary
Bin-Amphiphysin-Rvs (BAR) domain proteins remodel cell membranes. ACAP1
Area of Science:
- Cell biology
- Molecular biology
- Membrane trafficking
Background:
- Bin-Amphiphysin-Rvs (BAR) domain proteins are crucial for membrane remodeling.
- These proteins assemble into oligomers to influence membrane curvature.
Purpose of the Study:
- To investigate the function of the ACAP1 BAR domain in membrane deformation.
- To understand the role of ACAP1 in endosomal recycling.
Main Methods:
- Structural analysis of the ACAP1 BAR domain.
- Biochemical assays to assess membrane binding and deformation.
- Cellular imaging to track endosomal recycling.
Main Results:
- The ACAP1 BAR domain, despite structural similarity to other BAR domains, exhibits unique functional properties.
- Cooperation between the ACAP1 BAR domain and its adjacent pleckstrin homology domain is essential for membrane deformation.
- ACAP1 facilitates efficient endosomal recycling.
Conclusions:
- ACAP1 plays a significant role in membrane remodeling through its BAR domain.
- The interplay between BAR and pleckstrin homology domains in ACAP1 is key to its function in endosomal trafficking.

01:15Mechanisms of Membrane-bending
2.6K
The living membranes are flexible due to their fluid mosaic nature; however, their bending into different shapes is an active process regulated by specific lipids and proteins. The membrane bending can be transient as seen in vesicles or stable for a long time as in microvilli. Cells regulate the size, location, and duration of the membrane curvature.
Membrane bending can happen due to intrinsic changes in lipid composition or extrinsic association with different proteins. The proteins involved...

00:59Mechanisms of Membrane Domain Formation
3.2K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.

01:28Types of Membrane Protrusions
3.0K
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.

01:24Protein Diffusion in the Membrane
4.7K
Proteins show rotational as well as lateral diffusion across the membrane. The lateral diffusion of proteins was confirmed through the cell fusion experiment where mouse and human cells were fused, resulting in hybrid cells. When the human and mouse cells fused, the specific membrane proteins on human and mouse cells were marked with the red and green-fluorescent markers, respectively. Initially, the red and green fluorescence was located on the respective hemisphere of the cell. As time...

01:22Enlargement of the Plasma Membrane
1.7K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

01:26Membrane Fluidity
13.8K
Membrane fluidity is explained by the fluid mosaic model of the cell membrane, which describes the plasma membrane structure as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character.
Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is...
