What is protein domain and motifs?

A motif in protein structure refers to a chain-like biological structure made up of connectivity between secondary structural elements while a domain in protein structure refers to an independent folding unit of the three-dimensional protein structure.

What is a protein motif explain?

Protein motifs are small regions of protein three-dimensional structure or amino acid sequence shared among different proteins. They are recognizable regions of protein structure that may (or may not) be defined by a unique chemical or biological function.

What are protein domains?

Domains are distinct functional and/or structural units in a protein. Usually they are responsible for a particular function or interaction, contributing to the overall role of a protein.

What is the difference between motif and domain explain it with examples?

Motif is a certain grouping of the super secondary elements of proteins such as alpha helices and beta structures while domain is the functional unit of a protein. Furthermore, motif is a secondary structure while domain is responsible for the tertiary structure of the protein.

What is the role of protein domains?

Protein domains are the structural and functional units of proteins. It is now well established that proteins carry out their functions primarily through their constituent domains. They can be gained by proteins to acquire new function. Domains are, therefore, considered to be the units through which proteins evolve.

What is motif in bioinformatics?

A biological motif, broadly speaking, is a pattern found occurring in a set of biological sequences, such as in DNA or protein sequences. A motif could be an exact sequence, such as TGACGTCA , or it could be a degenerate consensus sequence, allowing for ambiguous characters, such as R for A or G .

What is motif in protein structure and sequence?

Protein sequence motifs are signatures of protein families and can often be used as tools for the prediction of protein function. The generalization and modification of already known motifs are becoming major trends in the literature, even though new motifs are still being discovered at an approximately linear rate.

How can you define domain and motif is there any significance in bioinformatics or in proteomics?

This is a structure that is seen in unrelated proteins that bind DNA, so the presence of a helix-turn-helix motif is an indication of a protein’s function. Domains, on the other hand, are regions of a protein that has a specific function and can (usually) function independently of the rest of the protein.
