HIF has two subunits, HIF-α (which has three further subunits HIF-1α, HIF-2α and HIF-3α) and HIF-β [ 17, 18].
Two further subunits, IL-13Rα2 and γc, seem to be ligand-specific: the γc subunit binds to IL-4 but not to IL-13 [ 40] while IL-13Rα2 binds exclusively to IL-13 [ 57].
The transfer of enzymes is rarer, mainly because a new enzyme has to be incorporated in a pre-existing metabolic pathway, and, further, subunits of protein complexes and proteins with multiple interactions seem to undergo fewer HGT events [ 15, 16].

This small molecule rapidly binds to natively folded TTR tetramers, arresting further subunit exchange while remaining nonfluorescent.
The catalytic core subunit is presenilin, an aspartyl intramembrane protease related to SPP, whereas a further subunit pre-selects peptide substrates and transfers them to the docking site in presenilin [ 46].
Aliquots of the subunit exchange reaction, taken as a function of time, are then added to an excess of a fluorogenic small molecule, which immediately arrests further subunit exchange.
This is also indicated by native mass spectrometry analyses of the quaternary ASB9 EloBC Cul5NTD complex; ASB9 EloBC Cul5NTD readily dissociates into ASB9 EloBC and Cul5NTD, but only small amounts of further subunit dissociation within ASB9 EloBC were seen.
In mammalian tissues, AMPK is a heterotrimer consisting of a catalytic α subunit with two further regulatory subunits, β and γ.
HyNaC4 does not assemble with HyNaC2 and HyNaC3 in a functional channel [ 3], suggesting the existence of further HyNaC subunits at the aboral side of the tentacles.
In further assessment, subunit vaccine was found to be immunogenic with the capability to generate humoral and cell-mediated immune response.
Both iso-complexes, Bet3 Tpc6A and Bet3 Tpc6B, are able to recruit Mum2, a further TRAPP subunit, and we identify the α1 α2 loop regions as a binding site for Mum2.
