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