rba_uniprot_features_search: Search UniProt protein sequence features

In rbioapi: User-Friendly R Interface to Biologic Web Services' API

Search UniProt protein sequence features

Description

UniProt maintains sequence annotations (features) that describe regions in the protein sequence. Using this function, you can search and retrieve UniProt proteins' sequence annotations (features). you may also refine your search query with variety of modifiers.

Usage

rba_uniprot_features_search(
  accession = NULL,
  gene = NULL,
  exact_gene = NULL,
  protein = NULL,
  reviewed = NULL,
  organism = NULL,
  taxid = NULL,
  categories = NULL,
  types = NULL,
  ...
)

Arguments

accession	UniProtKB primary or secondary accession(s). You can supply up to 100 accession numbers.
gene	UniProt gene name(s). You can supply up to 20 gene names. e.g. if you supply "CD40", "CD40 ligand" will also be included.
exact_gene	UniProt exact gene name(s). You can supply up to 20 exact gene names. e.g. if you supply "CD40", "CD40 ligand" will not be included in the results.
protein	UniProt protein name
reviewed	Logical: If TRUE, only return "UniProtKB/Swiss-Prot" (reviewed) entries; If FALSE, only return TrEMBL (un-reviewed) entries.
organism	Organism name.
taxid	NIH-NCBI Taxon ID. You can supply up to 20 taxon IDs.
categories	Sequence annotation (Features) categories (subsection). accepted values are: "MOLECULE_PROCESSING", "TOPOLOGY", "SEQUENCE_INFORMATION", "STRUCTURAL", "DOMAINS_AND_SITES", "PTM", "VARIANTS" and/or "MUTAGENESIS". You can supply up to 8 categories.
types	Sequence annotation (Features) types. accepted values are: "INIT_MET", "SIGNAL", "PROPEP", "TRANSIT", "CHAIN", "PEPTIDE", "TOPO_DOM", "TRANSMEM", "DOMAIN", "REPEAT", "CA_BIND", "ZN_FING", "DNA_BIND", "NP_BIND", "REGION", "COILED", "MOTIF", "COMPBIAS", "ACT_SITE", "METAL", "BINDING", "SITE", "NON_STD", "MOD_RES", "LIPID", "CARBOHYD", "DISULFID", "CROSSLNK", "VAR_SEQ", "VARIANT", "MUTAGEN", "UNSURE", "CONFLICT", "NON_CONS", "NON_TER", "HELIX", "TURN", "STRAND" and/or "INTRAMEM". You can supply up to 20 types.
...	rbioapi option(s). See rba_options's arguments manual for more information on available options.

Details

Note that this is a search function. Thus, you are not required to fill every argument; You may use whatever combinations of arguments you see fit for your query.
UniProt Entries are grouped in two sections:

1. Reviewed(Swiss-Prot): Manually annotated records with information extracted from literature and curator-evaluated computational analysis.

2. Unreviewed (TrEMBL): Computationally analyzed records that await full manual annotation.

Value

List where each element corresponds to one UniProt entity returned by your search query. The element itself is a sub-list containing all information that UniProt has about that entity.
