Q9BQS7

Hephaestin (Q9BQS7)

Uniprot ID Q9BQS7
Protein Name Hephaestin
Gene Name HEPH
Species Homo sapiens (Human)
Basic Information Experiments (1) Disease (0) Interactions
Signal peptide(a) N Secretome P(b) 0.464
Function May function as a ferroxidase for ferrous (II) to ferric ion (III) conversion and may be involved in copper transport and homeostasis. Implicated in iron homeostasis and may mediate iron efflux associated to ferroportin 1.

(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.
