Neurophysin I, carrier protein for Oxytocin


Protein Data Bank ID: 2HNU
Protein Name: Neurophysin I (Carrier for Oxytocin)
Organism: Bos taurus
Title of Drawing: Mother Bear with Baby

Neurophysin I together with oxytocin are both cleavage products of the precursor protein preprooxyphysin. Once preprooxyphysin has been cleaved, neurophysin acts as carrier protein for oxytocin. Oxytocin is a well-known hormone. It has many functions, especially in the field of human relationships. For example, it plays an important role in bonding between mother and child. Sometimes a view of a baby face is enough to induce a release of oxytocin.
So mother bear and its baby is a direct illustration of the function of oxytocin and hence its carrier protein neurophysin I.
Here
you can see a TED talk about the role of oxytocin. And here is an easy accessible video for the Russian-speaking readers.
