Search UniParc Entries

Use this function to search UniProt Archive (UniParc) entries. Search by identifier, annotation, organism, sequence properties, or other supported criteria. The rf_* arguments filter the cross-references returned within matching entries; they do not select entries by themselves.

Usage

rba_uniprot_uniparc_search(
  upi = NULL,
  accession = NULL,
  db_type = NULL,
  db_id = NULL,
  gene = NULL,
  protein = NULL,
  taxid = NULL,
  organism = NULL,
  sequence_checksum = NULL,
  ipr = NULL,
  signature_db = NULL,
  signature_id = NULL,
  upid = NULL,
  seq_length = NULL,
  rf_dd_type = NULL,
  rf_db_id = NULL,
  rf_active = NULL,
  rf_tax_id = NULL,
  ...
)

Arguments

upi: Character: (optional) Unique UniParc identifier(s). You can supply up to 100 IDs.
accession: Character: (optional) UniProtKB primary or secondary accession(s). You can supply up to 100 accession numbers.
db_type: Character: (optional) Cross-reference database name.
db_id: Character: (optional) Protein ID in a cross-reference database. You can supply up to 100 IDs.
gene: Character: (optional) UniProt gene name(s). You can supply up to 20 gene names.
protein: Character: (optional) UniProt protein name.
taxid: Numeric: (optional) NIH-NCBI Taxon ID. You can supply up to 20 taxon IDs.
organism: Character: (optional) Organism name.
sequence_checksum: Character: (optional) A 16-character hexadecimal sequence CRC64 checksum.
ipr: Character: (optional) InterPro identifier(s). You can supply up to 20 IDs.
signature_db: Character: (optional) InterPro signature database. You can supply up to 20 values.
signature_id: Character: (optional) Signature ID in an InterPro signature database. You can supply up to 20 IDs.
upid: Character: (optional) UniProt Proteome identifier (UPID). You can supply up to 100 UPIDs.
seq_length: Character or Numeric: (optional) An exact sequence length (e.g. 150) or a range of sequence lengths (e.g. "130-158").
rf_dd_type: Character: (optional) Filter each UniParc entry's content by cross-reference names. You can supply multiple values.
rf_db_id: Character: (optional) Filter each UniParc entry's content by protein identifiers in any cross-reference database. You can supply multiple values.
rf_active: Logical: (optional) Filter each UniParc entry's content by active status in the source database: TRUE retains active database references, FALSE retains inactive references, and NULL applies no active-status filter.
rf_tax_id: Numeric: (optional) Filter each UniParc entry's content by NIH-NCBI Taxon ID. You can supply multiple values.
...: rbioapi option(s). See rba_options's arguments manual for more information on available options.

Value

A list named by UniParc accession. Each element contains sequence information and cross-reference entries for one search hit.
