I am looking for a database, preferentially with a .csv or .txt dump that would be able to convert gene accession handles (Name, Gene Id, UNIPROT IDs, EMBL accession numbers, ...) to the chromosomes they are assigned in their specific organism.
This data is usually shown in web rendering of the Uniprot proteins, but is absent from the original .txt data dump as far as I know.

One way to do it is to grab the archive of the gene annotations from your source of choice with wget or curl, filter the result for genes with awk, and then convert to BED and awk to get the fourth and first columns (ID and chromosome values), e.g.,:
$ wget -qO- ftp://ftp.sanger.ac.uk/pub/gencode/Gencode_human/release_21/gencode.v21.annotation.gff3.gz \
| gunzip --stdout - \
| awk '$3=="gene"' - \
| convert2bed -i gff - \
| awk '{print "$4\t$1";}' - \
> gene_id_and_chromosome.txt
Thank you for your answer! I see there is a way to do the same thing for the mouse thanks to the same resource. Is there a way to retrieve the mapping for Saccharomyces Cerevisiae?
Take a look at the GFF or GTF files in the archives here, maybe this will help: http://downloads.yeastgenome.org/sequence/S288C_reference/genome_releases/?C=M;O=D
Hello Summer, hope you are doing well there! Cf my answer, hope it helps.
Could you be a little bit more explicit?

It seems that Uniprot has "Proteomes" object some of which actually map to the chromosomes.
In Uniprot, this is available under the DR; EMBL; BKXXXXX; ... ;. .. ;... field (for yeast, CMXXXX for humans).
A mapping from BKXXX (CMXXX) references seems to be obtainable manually from the Uniprot proteome links.
It seems that the mapping is also readily available in BioConductor among the gene location mapping tools too.
