protein

Protein sense and resolution

Record whether the subject is a protein class, specified molecule or preparation, including the peptide boundary convention.

1. Does this record represent a molecular protein, a protein family, a mixture or only a dietary protein measurement? definition
2. What convention distinguishes this entity from a peptide, and does another registry record already own the same sense? boundary

Reference sequence and chain set

Identify constituent chains, reference versions and the distinction between source organism and production host.

1. Which sequences, chain boundaries and identifiers define the protein, and which were experimentally verified? provenance
2. What is its biological source, and was this preparation isolated, recombinantly expressed or chemically synthesised? provenance

Observed covalent form

Record processing, mutations, tags, disulfides and other modifications without assuming uniform occupancy.

1. Which cleavage events, sequence changes, tags, crosslinks or covalent modifications distinguish the observed form from the reference? definition
2. Which modification sites and occupancies are measured, and does the observed mass support the assigned form? measurement

Folding and association state

Distinguish functional disorder or assembly from unfolding, unwanted association and aggregation.

1. What evidence establishes folded, disordered, unfolded or mixed conformations under the stated conditions? measurement
2. What chain stoichiometry, partner association and aggregate fraction are observed, and which states are expected for its function? measurement

Functional role evidence

Separate experimentally supported roles from predictions based on sequence or family membership.

1. Which catalytic, structural, transport, signalling, binding or other roles are supported, and in what biological context? definition
2. Which partners, cofactors, membranes or cellular locations are required, and what evidence supports those dependencies? provenance

Assayed functional performance

Record performance with assay conditions, controls and acceptance criteria.

1. Which assay endpoint, units, controls and conditions demonstrate the required function for this protein? measurement
2. What performance threshold must this preparation meet before the intended use can proceed? action

Quantified preparation composition

Record concentration, purity basis, formulation components and relevant contaminants.

1. How were protein concentration and target-form purity measured, and how do assay interferences affect the reported values? measurement
2. Which other proteins, nucleic acids, host-derived contaminants, residual reagents or formulation ingredients remain in the preparation? measurement

Stability and handling window

Track proteolysis, chemical alteration, precipitation, aggregation and activity loss over time.

1. Under which temperature, pH, buffer, concentration and time conditions were integrity and activity retained? measurement
2. What evidence determines acceptable storage, freeze-thaw exposure, reconstitution and criteria for retesting or disposal? action

Protein quantity and quality

Distinguish measured protein content from nitrogen-based estimates and assess composition and digestibility.

1. Is reported protein content directly measured or inferred from nitrogen, and which conversion factor and non-protein nitrogen correction were used? measurement
2. What amino-acid composition and digestibility evidence applies to this preparation, processing state and intended consumer population? measurement

Evidence-based use disposition

Record allergenic, toxic, immunogenic or other relevant hazards and applicable use requirements without assigning universal properties to all proteins.

1. What evidence addresses hazards of this protein and its contaminants for the intended exposure route, dose and population? provenance
2. Which substance identifiers, hazard classifications and grade or jurisdiction requirements apply to this exact preparation and intended use? action
