Definition

Three-dimensional protein structural elements that are composed of a combination of secondary structures. They include HELIX-LOOP-HELIX MOTIFS and ZINC FINGERS. Motifs are typically the most conserved regions of PROTEIN DOMAINS and are critical for domain function. However, the same motif may occur in proteins or enzymes with different functions.

Common questions about Amino Acid Motifs

What does Amino Acid Motifs mean in medicine?
Three-dimensional protein structural elements that are composed of a combination of secondary structures. They include HELIX-LOOP-HELIX MOTIFS and ZINC FINGERS. Motifs are typically the most conserved regions of PROTEIN DOMAINS and are critical for domain function. However, the same motif may occur in proteins or enzymes with different functions. This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Amino Acid Motifs known by any other names?
Yes. Amino Acid Motifs is also referred to as Amino Acid Motif, Motif, Amino Acid, AA Motifs, AA Motif in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
Where does Amino Acid Motifs sit in the medical classification?
Amino Acid Motifs falls under the broader medical category "Phenomena and Processes" in the MeSH hierarchy (tree numbers: G02.111.570.820.709.275.500, G02.111.570.820.709.600.500). Browsing the related concepts on this page takes you to neighbouring topics in the same branch of medicine.
