A protein's 3D structure is what determines, or partially determines, its function.

Judge against the scientific consensus in structural biology as of April 2026. True: standard references and the literature hold that a protein's 3D structure is central to, and largely determines, its function. Mostly true: the consensus holds that structure is important but stresses major qualifications that the claim does not mention, such as intrinsically disordered proteins and the role of dynamics. Mixed: structure's role in function is substantially disputed in the literature. Mostly false: structure is shown to be only a minor factor in protein function. False: the evidence shows structure is not related to function.

   “In proteins, amino acids are linked together in long strings that fold up to make a three-dimensional structure, which is decisive for the protein’s function.”

2. E2 Functions of short lifetime biological structures at large: the case of intrinsically disordered proteins Oxford Academic (Briefings in Functional Genomics) · 22 January 2020

   “It is recognized now that although unique 3D structure represents a crucial prerequisite for many biological functions ascribed to proteins (e.g. catalysis and transport), not all protein functionality is 3D structure-dependent.”

   “However, protein function is not solely determined by static three-dimensional structures but is fundamentally governed by dynamic transitions between multiple conformational states.”

4. E4 Intrinsic Disorder and Protein Function Not stated on the fetched page (authors at Washington State University and Temple University)

   “The dominant view of protein structure-function is that an amino acid sequence specifies a (mostly) fixed three-dimensional (3-D) structure that is a prerequisite to protein function.”

The Nobel Committee's 2024 press release says a protein's folded three-dimensional structure is "decisive for the protein's function" (E1), and E4 describes the dominant view as holding that a (mostly) fixed 3D structure is a prerequisite to function. That supports the claim that 3D structure is central to function. However, the literature adds major qualifications, such as that not all protein function depends on 3D structure (E2) and that dynamic transitions between conformational states govern function (E3), which the claim does not spell out beyond saying structures "partially determine" function. E2 says it "is recognized now" that not all protein function depends on 3D structure, pointing to intrinsically disordered proteins. E3 says function is not determined solely by static structures and is fundamentally governed by changes between conformational states, which fits the criteria's description of "mostly true".
