Function

Involved in the development of the olfactory system and in neuronal control of puberty. Induces the collapse and paralysis of neuronal growth cones. Could serve as a ligand that guides specific growth cones by a motility-inhibiting mechanism. Binds to the complex neuropilin-1/plexin-1.
Involvement in disease

Hypogonadotropic hypogonadism 16 with or without anosmia
Sequence similarities

Belongs to the semaphorin family.
Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 PSI domain.
Contains 1 Sema domain.
Domain

Strong binding to neuropilin is mediated by the carboxy third of the protein.
Cellular localization

Secreted.

Lane 1: PC-12 whole cell lysate, 10 μg (Input).

Lane 2: ab199475 IP in PC-12 whole cell lysate.

Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab199475 in PC-12 whole cell lysate.

Blocking and dilution buffer and concentration: 5% NFDM/TBST.

Exposure time: 3 seconds.

Staining pattern is consistent with what has been described in the literature, PMID: 23469280.
