CASP2 identity and boundary Establish what the registry name denotes before attaching molecular observations.

Reference anchor

Resolve the symbol against an organism-qualified authority record.

Human gene anchor

NCBI identifies human CASP2 as a protein-coding gene, Gene ID 835, linked to HGNC:1503; this establishes a candidate interpretation, not the registry's intended referent. [NCBI CASP2](https://www.ncbi.nlm.nih.gov/gene/835)

  1. Does the originating registry record identify human CASP2, another organism's ortholog or the protein? definition
  2. Which original identifier and source support mapping vr.tr.casp2 to this reference? provenance

Molecular and species boundaries

Keep related biological entities connected without making them interchangeable.

Gene, product and ortholog separation

Require explicit relationships between the CASP2 gene, its RNA products, caspase-2 proteins and orthologous genes.

  1. Is this observation about CASP2 DNA, RNA or caspase-2 protein? boundary
  2. Does the catalogue already contain the same molecular concept under caspase-2 or another identifier? boundary
CASP2 sequences and products Represent the sequence distinctions needed to interpret CASP2 observations.

Transcript-product mapping

Connect each measured or manipulated transcript to its supported protein product.

Isoform resolution

Human CASP2 has alternatively spliced transcripts encoding multiple isoforms; measurements should retain their actual resolution. [NCBI CASP2](https://www.ncbi.nlm.nih.gov/gene/835)

  1. Which versioned transcript and protein accessions describe the isoform under study? definition
  2. Can the primers, reads or detected peptides distinguish that isoform from other CASP2 products? measurement

Variants and constructs

Record departures from the chosen CASP2 reference sequence.

Sequence change attribution

Separate natural alleles from engineered mutations, truncations and tags before generalizing observations to endogenous CASP2.

  1. Which substitutions, deletions, tags or domain boundaries distinguish this construct from its CASP2 reference? definition
  2. What sequence verification supports the reported allele or construct identity? provenance
CASP2 expression and protein state Distinguish how much CASP2 product is present from its processing and activity.

Expression context

Interpret CASP2 abundance in its sampled biological setting.

Contextual abundance

Require the molecular target, sample context and normalization for every CASP2 abundance observation.

  1. Which organism, tissue or cell system, treatment and time point produced the CASP2 measurement? provenance
  2. Does the result quantify total CASP2 RNA, a particular transcript or a defined protein form, and in what units? measurement

Processing and catalysis

Keep evidence of protein cleavage separate from evidence of catalytic function.

Activity attribution

Assess caspase-2 processing and substrate cleavage as separately supported observations.

  1. Which caspase-2 molecular forms or cleavage products were directly detected? measurement
  2. Which substrate, assay conditions and controls establish that the activity signal depends on caspase-2? measurement
  3. What additional evidence is needed before labelling this caspase-2 preparation active? action
CASP2 function and causal evidence Evaluate what CASP2 perturbations and molecular associations establish in a defined biological context.

Perturbation interpretation

Connect an intervention to its verified molecular effect and measured outcome.

CASP2-dependent phenotypes

Record the evidence needed to distinguish effects of CASP2 loss or alteration from assay artifacts and other intervention effects.

  1. How was CASP2 deletion, knockdown, overexpression or inhibition verified at the relevant molecular level? measurement
  2. Do independent perturbations or an appropriate CASP2 rescue support attribution of the phenotype? provenance
  3. Which organism, cell state and experimental conditions bound the functional conclusion? boundary

Mechanistic relationships

Separate direct CASP2 product interactions from downstream pathway associations.

Interaction and substrate evidence

Qualify proposed caspase-2 partners and substrates by the type and context of supporting evidence.

  1. Does the experiment establish direct binding, complex membership, direct cleavage or only a downstream association? boundary
  2. Which controls and independent observations support the proposed caspase-2 partner or substrate relationship? provenance
  3. What experiment would distinguish a catalytic caspase-2 effect from another consequence of CASP2 perturbation? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

Reported evidence

Findings from the breadth pass, kept separate from the structural claims.

What it is Filled

CASP2 is the approved symbol for the human gene encoding caspase-2, a cysteine protease involved in cellular stress responses and regulated cell death.

In scope

  • CASP2 identity, organism and reference identifiers
  • Gene-to-transcript-to-protein relationships
  • Sequence variants and experimental constructs attributed to CASP2
  • CASP2 expression and caspase-2 molecular state
  • Evidence connecting CASP2 perturbation to observed cellular effects

Out of scope

  • Other caspase genes and their independent models
  • Complete models of apoptosis or cellular stress responses
  • Diseases associated with CASP2 as independent clinical entities
  • Antibody, inhibitor and assay-kit products as commercial objects
  • Whole genomes, organisms and cell lines beyond their relationship to CASP2

Why it exists Filled

Enable an agent to identify CASP2, distinguish its gene, transcript and protein representations, and judge which experimental observations support claims about its expression or function.

Distinguishing features Filled

  • For the provisional human interpretation, require agreement with NCBI Gene 835 or HGNC:1503, rather than accepting the symbol alone.
  • Distinguish the CASP2 DNA locus from an RNA transcript or caspase-2 protein by molecule type and accession.
  • Require organism identification before treating similarly named genes as the same entity rather than orthologs.
  • Resolve transcript or protein isoforms by sequence accession and version; a shared CASP2 label does not establish sequence identity.
  • Do not treat a general caspase activity signal as identification of caspase-2 without evidence that distinguishes other caspases.

What robots and AI may and may not do Filled

Must not

  • Interpret a person's CASP2 variant as a diagnosis.
  • Share genetic data without consent.
  • Present early research on caspase-2 as available treatment.
  • Confuse caspase-2 with other caspases when reporting findings.

Only with a human decision

  • Using results in clinical decisions.
  • Research on patient samples without documented consent.

May

  • Describe CASP2 and the caspase-2 enzyme's role in stress responses and cell death, citing sources.
  • Report what an experimental or variant result shows, with source and limits.

Moral aspects Filled

  • Overstated links between genes and disease can cause needless fear.
  • Genetic data is private and identifying.
