do·main

(dō-mān'),
1. Homologous unit of approximately 110-120 amino acids, groups of which make up the light and heavy chains of the immunoglobulin molecule; each serves a specific function. The light chain has two domains, one in the variable region and one in the constant region of the chain; the heavy chain has four to five domains, depending on the class of immunoglobulin, one in the variable region and the remaining ones in the constant region.
2. A region of a protein having some distinctive physical feature or role.
3. An independently folded, globular structure composed of one section of a polypeptide chain. A domain may interact with another domain; it may be associated with a particular function. Domains can vary in size.

domain

  1. a structurally or functionally distinct part of a PROTEIN.
  2. any of three primary groupings (‘superkingdoms’): ARCHAEA, BACTERIA or EUCARYA, into which all ORGANISMS are placed in modern CLASSIFICATIONS based on genetic structures and sequences.

Patient discussion about domain

Q. What other illnesses are similar to asthma? I am 45 years old. My doctor suspects I might have adult asthma but there has yet been a final diagnosis made. What other problems might this be?

A. Before diagnosing someone as asthmatic, alternative possibilities should be considered. A clinician taking a history should check whether the patient is using any known bronchoconstrictors (substances that cause narrowing of the airways, e.g., certain anti-inflammatory agents or beta-blockers). Chronic obstructive pulmonary disease, which closely resembles asthma, is correlated with more exposure to cigarette smoke, an older patient, and decreased likelihood of family history of atopy. Your physician should examine these possibilities as well before diagnosing.
