Protein subunit assembly

Post by jane1011 » Sun Jan 15, 2012 8:36 pm

Are protein subunits always associated or might it be possible that a certain protein modification is required in order for a (e.g. regulatory) subunit to associate with the other subunits?

look for example to G-protein coupled receptors. They have three subunits which dissociate after receiving signal

Cis or trans? That's what matters.
