It has been speculated that the five membrane-spanning segments of CD47/IAP and the two membrane-spanning domains of the heterodimeric integrin form an ad hoc seven-transmembrane receptor that, with an adhesive ligand such as TSP, could activate GTPase activity in a manner analogous to that of conventional heptaspanins [ 41].
It has consequently been speculated that the two proteins may have a redundant function in the respiratory tract, which is also supported by the observation that gene transfer with a vector-encoding mClca5 also induces airway mucus production (Patel et al. 2006).
It has been speculated that LARP may one day evolve into a major industry in the form of location-based games using ubiquitous computing.
