Interleukin-1 receptor antagonist protein (P25086)

Uniprot ID P25086
Protein Name Interleukin-1 receptor antagonist protein
Gene Name Il1rn
Species Rattus norvegicus (Rat)

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
