Use SPIN to submit sequences determined at protein level and associated functional annotation to UniProtKB.
What does at protein level mean?
Edman degradation or manual interpretation of MS/MS spectra. See also the help section or ask us.
Do you have a translated nucleotide sequence?
Submit to ENA
Do you have a sequence identified using a search engine (e.g. Mascot, SEQUEST, X! Tandem, OMSSA, MS-GF+, Skyline, MaxQuant/Andromeda)? Submit to PRIDE
