Description

Section titled “Description”

RefSeq recombination intervals from explicit genomic GFF3 rows.

This includes recombination-signal sequences associated with immune-gene segments.

Partitions

  • assembly_accession
    • 'GCF_000001405.25'
    • 'GCF_000001405.40'

Schema

Section titled “Schema”
Column Type Description
sources STRUCT(url TEXT, filename TEXT, last_modified_at TIMESTAMPTZ, sha256 TEXT)[] Original external inputs used to produce the row. Each item contains its source URL, filename, HTTP Last-Modified timestamp when available, and computed SHA-256 checksum.
assembly_accession TEXT Partition column. Versioned RefSeq assembly accession (GCF accession).
sequence_accession TEXT Versioned RefSeq nucleotide sequence accession on which the recombination feature is annotated; joins refseq.assembly_sequences.sequence_accession.
start INT 1-based inclusive start coordinate of the recombination-feature interval on sequence_accession.
end INT 1-based inclusive end coordinate of the recombination-feature interval on sequence_accession.
is_forward_strand BOOLEAN Whether the recombination-feature interval is on the forward strand; null when the GFF strand is unspecified.
recombination_feature_id TEXT Local GFF3 ID of the recombination feature; not a stable RefSeq identifier.
recombination_type TEXT Source GFF3 recombination feature type.
annotation_method TEXT NCBI GFF column-2 annotation method or source, if supplied.
db_xrefs STRUCT(db TEXT, id TEXT)[] Database cross-references from GFF Dbxref; each item has a database and identifier, which may contain colons.
associated_gene_symbol TEXT Gene symbol from GFF gene, if supplied. This is an annotation rather than a local GFF gene-ID join; use db_xrefs for identifier-based matching.
associated_gene_name TEXT Associated gene or segment name from GFF standard_name, if supplied.
is_pseudogene BOOLEAN Whether GFF pseudo=true marks the associated recombination feature as pseudogenic.
recombination_class TEXT NCBI recombination category from GFF recombination_class, if supplied, such as meiotic, mitotic, non-allelic homologous, chromosome breakpoint, or recombination hotspot.
experiments TEXT[] Percent-decoded experimental-evidence entries from the comma-separated GFF experiment attribute.
is_partial BOOLEAN Whether NCBI marks the recombination feature as partial with GFF partial=true.
is_start_partial BOOLEAN Whether NCBI marks the column-4 start boundary as partial with a GFF start_range attribute.
is_end_partial BOOLEAN Whether NCBI marks the column-5 end boundary as partial with a GFF end_range attribute.
note TEXT Free-text GFF Note annotation, if supplied.
