F-BAR domain proteins: Families and function
Communicative & Integrative Biology
|June 30, 2010
Summary
The F-BAR domain is crucial for membrane remodeling and actin dynamics. Our study categorizes F-BAR proteins, revealing key interactions influencing their cellular functions.
Area of Science:
- Cell Biology
- Molecular Biology
- Protein Domain Analysis
Background:
- The Fer-bin-Amphiphysin-Rvs (F-BAR) domain is increasingly recognized for its role in membrane remodeling.
- F-BAR domain proteins link membrane shaping with actin cytoskeleton dynamics, impacting processes like endocytosis and filopodium formation.
Purpose of the Study:
- To conduct a comprehensive analysis of F-BAR domain proteins.
- To investigate their evolutionary relationships and functional roles within cellular pathways.
Main Methods:
- Phylogenetic analysis to categorize F-BAR domain proteins into subfamilies.
- Identification and analysis of associated protein domains (e.g., RhoGAP, SH3).
- Construction of a protein-protein interaction network.
Main Results:
- F-BAR domain proteins were classified into five distinct phylogenetic subfamilies.
- These subfamilies correlate with the presence of specific functional domains.
- A protein-protein interaction network highlighted central roles for dynamin1/2, N-WASP, Huntingtin, intersectin, and Cdc42.
Conclusions:
- The evolutionary relationships and domain composition provide a framework for understanding F-BAR protein function.
- Key protein interactions identify critical regulators of F-BAR domain protein activity in cellular processes.

02:47Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...

02:26Conservation of Protein Domains Over Different Proteins
Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to form...

01:09Multi-pass Transmembrane Proteins and β-barrels
In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

01:18Membrane Domains
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.

The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the anterior...

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...
