In UniProt, an entry such as Q8N4C6 has Gene: NIN but in the Gene Names field

Name: NIN
Synonyms:KIAA1565

If I select the genes column, I get both names.

> select(up, "Q8N4C6", "GENES", "UNIPROTKB")
Getting extra data for Q8N4C6
'select()' returned 1:1 mapping between keys and columns
  UNIPROTKB        GENES
1    Q8N4C6 NIN KIAA1565

How can I get just the representative gene symbol (i.e. Approved Symbol by HGNC) like is shown at the top of the summary web page for Q8N4C6? I'm uncertain if the official symbol is always reported first in the genes column. I suppose that I'm hoping there was a select(up, "Q8N4C6", "GENE", "UNIPROTKB") command available.

Right now UniProt.ws is querying the REST API using the 'genes' keyword, so the query you end up passing is

https://www.uniprot.org/uniprot/?query=Q8N4C6&format=tab&columns=id,genes

Which will return all HGNC symbols for that protein. Since KIAA1565 got wrapped into NIN back in 2005, you get both, because technically both gene symbols apply. There is however a preferred symbol, which you can get using

https://www.uniprot.org/uniprot/?query=Q8N4C6&format=tab&columns=id,genes(PREFERRED)

Hypothetically we could add this to UniProt.ws, but there are other ways of doing things that are even easier:

> select(org.Hs.eg.db, "Q8N4C6", "SYMBOL","UNIPROT")
'select()' returned 1:1 mapping between keys and columns
  UNIPROT SYMBOL
1  Q8N4C6    NIN

Which, all things equal, should be the go-to solution.

Not a solution using uniprot.ws but if you query directly using the REST API you get a single gene symbol returned, which is presumably always the same as the one that appears on the summary pages.

library(httr)
my_protein_ids <- c('Q8N4C6', 'Q9UM73')

results <- POST(url = "https://www.uniprot.org/uploadlists/",
                body = list(from = 'ID',
                            to = 'GENENAME',
                            format = 'tab',
                            query = paste(my_protein_ids, collapse = ' ')))

uniprot_results <- content(results, type = 'text/tab-separated-values', 
                           col_names = TRUE, 
                           col_types = NULL, 
                           encoding = "UTF-8")

Is it possible to apply this code to a column of Swissprot IDs (in an excel file)? As this results from proteomics analysis, some proteins are ambiguous.

I tried this, but get a wrong output below:

library(httr)
data <- read_xlsx("reference_set.xlsx", col_names = TRUE)
my_protein_ids <- data$proteins

results <- POST(url = "https://www.uniprot.org/uploadlists/",
                body = list(from = 'ID',
                            to = 'GENENAME',
                            format = 'tab',
                            query = paste(my_protein_ids, collapse = ' ')))

uniprot_results <- content(results, type = 'text/tab-separated-values', 
                           col_names = TRUE, 
                           col_types = NULL, 
                           encoding = "UTF-8")

output:

<html> 1 <head><title>405 Not Allowed</title></head> 2 <body> 3 <center>

405 Not Allowed

</center> 4
<center>nginx/1.21.6</center> 5 </body> 6 </html>

Here is a sample of the IDs:

I think Jim's answer above using select still applies but it is also possible with UniProt.ws.

Note that this only works for valid UniProt accession identifiers from your list. This means that IDs such as Y-FGCZCont00180 may not work.

library(UniProt.ws)
mapUniProt("UniProtKB_AC-ID", "UniProtKB", query = c("Q9BVI4", "Q12802"))
