NUCKS1 (Q9H1E3) - a RAD51AP1 paralogue that binds the same DNA with weaker affinity, and whose measured phenotype is mitomycin-C sensitivity rather than the D-loop binding this graph reached for

[]

{
  "partner": "RAD51AP1",
  "relationship": "extensive sequence homology; the primary paper calls them paralogues",
  "the_functional_asymmetry": "recombinant NUCKS1 shares the SAME DNA binding preference as RAD51AP1 but binds DNA with REDUCED affinity",
  "phenotypic_similarity": "NUCKS1 depletion phenocopies RAD51AP1 knockdown for impaired HR and chromosome instability",
  "why_this_matters_for_this_project": "a paralogue pair where one member is the weaker version of the other is exactly the shape this project's registry warns about - a swap between them would not produce an obviously wrong entry, it would produce a quantitatively wrong one. gene-rad51ap1 does not exist in this graph."
}

{
  "homologous_recombination": "depletion impairs DNA repair by HR and chromosome stability; NUCKS1 is described as critical to maintaining wild-type HR capacity",
  "crosslink_sensitivity": "greatly increased cellular sensitivity to mitomycin C, with increased spontaneous AND MMC-induced chromatid breaks",
  "replication": "functional loss slows replication fork progression with a concomitant increase in the utilisation of new replication origins",
  "which_connects_where": "MMC is the canonical interstrand-crosslink agent, so the crosslink phenotype connects to this graph's ICL/Fanconi beat rather than to its R-loop beat"
}

{
  "what_i_wrote": "that NUCKS1 binds 'secondary DNA structures such as D-loop structures' and that D-loop binding 'sits between the break-repair beat and the R-loop beat'",
  "the_problem": "the D-loop phrase is UniProt's curation and the primary paper's abstract does not mention D-loops",
  "measured": {
    "(NUCKS1 OR NUCKS) AND \"D-loop\"[tiab]": "0 - GENUINE zero, parsed querytranslation with warninglist 'No items found.'",

    "(NUCKS1 OR NUCKS) AND \"homologous recombination\"[tiab]": 4
  },
  "so": "the R-loop connection I reached for has an empty literature under either token, and the entry stands on the HR and MMC phenotypes instead. The adjudication entry has been amended."

  "reading": "near-disjoint on a tiny total literature. Both tokens were run per the registry rule that the alias question has no default direction; here the approved symbol is the larger set but the overlap is a single record, so neither token alone describes the literature.",
  "a_token_tested_and_discarded": "P1[tiab] returns 42,355 records and is unusable as an operand for this gene. It was tested speculatively and is NOT asserted here to be a UniProt-listed synonym - the UniProt record returned no gene synonyms for NUCKS1."
