motif(of a PROTEIN) a specific combination of SECONDARY STRUCTURES exhibiting a characteristic three-dimensional structure and often associated with a particular function. For example, the coiled-coil motif, comprising of two or more helices wound around each other. This is found in the GLYCOPROTEIN of EBOLA VIRUS and has a role in entry of the virus into host cells. Also the ZINC FINGER which comprises of an α helix and two β strands forming a finger-like structure held together by a zinc ion.

Patient discussion about motif
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.More discussions about motif
