Insulin-like growth factor-binding protein 3 (P17936)

Uniprot ID P17936
Protein Name Insulin-like growth factor-binding protein 3
Gene Name IGFBP3
Species Homo sapiens (Human)
Signal peptide(a) Y Secretome P(b) 0.841
Function IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R. .

(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.
