Summary
The AAA ATPase p97 (also known as VCP) interacts with various cellular adaptors. Understanding these interactions is key to deciphering p97
Area of Science:
- Cellular Biology
- Molecular Biology
- Biochemistry
Background:
- The AAA ATPase p97 (Valosin-containing protein, VCP) is crucial for ubiquitin signaling.
- p97 function is modulated by numerous adaptor proteins.
- Understanding p97-adaptor interactions is vital for elucidating its physiological roles.
Purpose of the Study:
- To review current knowledge on how adaptor proteins bind to p97.
- To highlight the structural basis of p97-adaptor interactions.
- To explore common binding mechanisms among p97 adaptors.
Main Methods:
- Structural characterization of p97 interactions with specific adaptor domains (PUB, UBX, UBD).
- Identification and analysis of short p97-interacting motifs (VBM, VIM, SHP).
- Review of existing literature on p97-adaptor binding.
Main Results:
- Structural studies reveal conserved binding modes for UBX and UBD domains.
- Short motifs like VBM, VIM, and SHP are shared among adaptors.
- Shared motifs suggest potentially common binding mechanisms.
Conclusions:
- p97 binding to adaptors is mediated by specific domains and motifs.
- Structural homology and shared motifs imply conserved interaction principles.
- Further research into these interactions will clarify p97's diverse cellular functions.

01:33Coat Assembly and GTPases
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

01:26Tension Response at Adherens Junctions
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
α-Catenin as a Mechanosensory Protein
The α-catenin of adherens junctions is an allosteric protein with three VH (vinculin homology) domains...

01:42The ADP/ATP Carrier Protein
ADP/ATP carrier or AAC protein is the most abundant carrier protein in the inner mitochondrial membrane. It transports large quantities of ADP and ATP, equivalent to the average human body weight, every day. Among other transporters, ACC protein is one of the best-studied members of the mitochondrial carrier protein family. The ADP/ATP carrier protein comprises two transmembrane helices connected to a loop and a single alpha-helix on the matrix side. It switches between two conformational...
01:23Catenins
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...

01:49Conserved Binding Sites
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...

00:49Ligand Binding and Linkage
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence the...
