PMID: 29774236
DOI: 10.1126/sciadv.aar4536

[…] membrane. As a follow-up to these observations, we used bioinformatics to determine whether the protein had a predicted signal peptide or a chloroplast targeting sequence. The combined algorithms of SignalP v.3.0 (using neural networks) and ASAFind suggest that ISIP1 has a predicted N-terminal signal peptide but that it is not targeted to the chloroplast because it lacks the FWYL residue at +1 of […]


Comparative Genomics Reveals the Core Gene Toolbox for the Fungus Insect Symbiosis

PMCID: 5954228
PMID: 29764946
DOI: 10.1128/mBio.00636-18

[…] tein length (). CEGMA v2.4.010312 was used to identify the presence of core eukaryotic-protein-coding genes and for subsequent evaluation of genome coverage (). Secreted proteins were predicted using SignalP v4.1 (no truncation to the sequence length) (), and transmembrane helices were predicted using TMHMM v2.0 (). Potential pathogenic proteins were identified using BLASTP against pathogen-host i […]


Papain like and legumain like proteases in rice: genome wide identification, comprehensive gene feature characterization and expression analysis

BMC Plant Biol
PMCID: 5952849
PMID: 29764367
DOI: 10.1186/s12870-018-1298-1

[…] To gain insight into potential subcellular location of each OsCP and OsVPE, signal peptide predication of each protein using SignalP 4.1 was firstly carried out []. The results revealed that all OsCPs and OsVPEs contain a predicted signal peptide, indicating that all members in these two families could enter the endomembran […]


Immune Informatic Analysis and Design of Peptide Vaccine From Multi epitopes Against Corynebacterium pseudotuberculosis

Bioinform Biol Insights
PMCID: 5954444
PMID: 29780242
DOI: 10.1177/1177932218755337

[…] To verify the peptide signal and consequently locate the C pseudotuberculosis, the SignalP 4.1 software was used (available at This tool contains 2 neural networks, where it is possible to select sequence options with or without transmembrane sets. […]


Characterisation of proteins in excretory/secretory products collected from salmon lice, Lepeophtheirus salmonis

PMCID: 5948691
PMID: 29751843
DOI: 10.1186/s13071-018-2885-6
call_split See protocol

[…] To investigate secretory involvement, signal peptide predictions were made from the translated cDNA sequence representing each protein using SignalP prediction software (CBS). Identified proteins were investigated using the Blast2Go software suite []. Sequences were blasted against the NCBInr database. Proteins were then assigned into func […]
