Semaphorin-3F is a protein that in humans is encoded by the SEMA3F gene.The semaphorins are a family of proteins that are involved in signaling. All the family members have a secretion signal a 500-amino acid sema domain and 16 conserved cysteine residues (Kolodkin et al. 1993). Sequence comparisons have grouped the secreted semaphorins into 3 general classes all of which also have an immunoglobulin domain.
