A protein domain is a conserved part of a given protein sequence and (tertiary) structure that can evolve, function, and exist independently of the rest of the protein chain. Each domain<span> forms a compact three-dimensional structure and often can be independently stable and folded.
On the other hand, a motif is a </span>distinctive sequence<span> on a protein or DNA, having a three-dimensional structure that allows binding interactions to occur. Early on, clustering was used to detect common three-dimensional structural motifs in </span>proteins<span>.

An allergy
An allergy is a disorder caused
by an abnormal reaction to a harmless antigen in the environment. These
diseases include food allergies, hay fever, atopic dermatitis and allergic
asthma. Symptoms may include, a runny nose, shortness of breath, swelling red
eyes, or sneezing. Non-allergic individuals tolerate allergens without problems.
The two main types of allergic reactions are immediate hypersensitivity and delayed
hypersensitivity.
