Figure 4: iRhom1-dependent brain shedding substrates are substrates for ADAM17.
Adam17+/+ (black) and Adam17−/− (red) MEFs overexpressing substrate candidates carrying an alkaline phosphatase (AP)-tag were treated with or without PMA for 45 min (N=3). The AP activity in the conditioned media was normalized to the expression level as well as to the untreated sample. P-values indicated in brackets for all significantly upregulated shed ectodomains upon PMA stimulation: TGFα (1.13E-03), EPHB6 (1.49E-03), MEGF10 (1.42E-04), MRC2 (3.75E-04), SEMA5B (2.9E-04) (unpaired t-test). (** p-value < 0.01, *** p-value < 0.001)
