Myt Iso-seq Annoation


July 24, 2023


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.

/home/shared/ncbi-blast-2.11.0+/bin/makeblastdb \
-in ../data/uniprot_sprot_r2023_02.fasta \
-dbtype prot \
-out ../analyses/blast/uniprot_sprot_r2023_02
head -4 ../data/Mtros-hq_transcripts.fasta

grep ">" ../data/Mtros-hq_transcripts.fasta | head

-query ../data/Mtros-hq_transcripts.fasta \

-out ../analyses/blast/ \
-evalue 1E-20 \
-num_threads 40 \

-max_hsps 1 \
-outfmt 6

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/
## MT_Pool_HQ_transcript/0  sp|D3ZHA0|FLNC_RAT  42.357  2486    1247    48  1977    8993    278 2724    0.0 1647

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) %>%
write.table(file = "../analyses/blast/Mtros_GO.txt", sep = #"\t", row.names = FALSE, quote = FALSE
