Mytilus trossulus Iso-seq Annotation


In this following chunk where the fasta file is downloaded the release is noted and the file name is modified accordingly.

cd ../data

curl -O

mv uniprot_sprot.fasta.gz uniprot_sprot_r2023_02.fasta.gz
gunzip -k uniprot_sprot_r2023_02.fasta.gz

A protein blast database is then made.

-in ../data/uniprot_sprot_r2023_02.fasta \
-dbtype prot \
-out ../analyses/blast/uniprot_sprot_r2023_02

Here is what the output file looks like, and at this point we want to get the UniProt Accession number for each gene

head -2 ../analyses/blast/

blast <- read.csv("../analyses/blast/", sep = '\t', header = FALSE)
blastsp <- blast %>%
  mutate(SPID = str_extract(V2, "(?<=\\|)[^\\|]*(?=\\|)"))

Now lets just write out SPIDs.

blast %>%
  mutate(SPID = str_extract(V2, "(?<=\\|)[^\\|]*(?=\\|)")) %>%
  distinct(V1, SPID, .keep_all = TRUE) %>%
  select(SPID) %>%
  write.table(file = "../analyses/blast/SPID.txt", sep = "\t", row.names = FALSE, quote = FALSE

With a list of matching Swiss-Prot IDs, (technically UniProt Accession number) we can go back to and grab corresponding GO terms. This can be done via a web or using Python API.

python3 ../analyses/blast/SPID.txt
mv uniprot-retrieval.tsv.gz ../analyses/blast/uniprot-retrieval.tsv.gz

gunzip ../analyses/blast/uniprot-retrieval.tsv.gz


idmap <- read.csv("../analyses/blast/idmapping_2023_08_07.tsv", sep = '\t', header = TRUE, row.names=NULL)


left_join(blastsp, idmap, by = c("SPID" = "Entry")) %>%
  select(V1, V2, V11, Protein.names, Gene.Ontology..biological.process., Gene.Ontology.IDs) %>%
