iRhom2 is an essential cofactor for ADAM17, the metalloprotease that sheds both the proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) and TNF receptors (TNFRs) from the cell surface. In this issue of Science Signaling, Sundaram et al. demonstrate a protective role for iRhom2 in promoting ADAM17-mediated shedding of TNFRs in hepatic stellate cells, which reduces TNFR signaling and liver fibrosis in response to injury.

Systemic and cellular metabolism: the cause of and remedy for disease?

Colin Adrain

Summary: The word 'metabolism' comes from the Greek term metavoli (metabole), meaning 'change'. It is now understood that cell behavior is closely linked to metabolism, and disruptions in metabolite abundance or flux can deeply affect cellular (and whole-body) function, leading to disease. Metabolism plays a crucial role in both health and disease, with most diseases being considered metabolic diseases; modulating metabolism may be key in changing disease outcomes.

EMC is required for biogenesis of Xport-A, an essential chaperone of Rhodopsin-1 and the TRP channel

Catarina J. Gaspar, Ligia C. Vieira, Cristiana C. Santos, John C. Christianson, David Jakubec, Kvido Strisovsky, Colin Adrain, Pedro M. Domingos

Summary: The ER membrane protein complex (EMC) is essential for the biogenesis of a subset of tail anchored (TA) and polytopic membrane proteins in Drosophila, including Rhodopsin-1 (Rh1) and the TRP channel. This study identified that EMC is required for the biogenesis of the proteins fan and Xport-A, where Xport-A plays a crucial role in the biogenesis of both Rh1 and TRP. Additionally, it was found that Xport-A is involved in a glycosylation-dependent triage mechanism during Rh1 biogenesis in the endoplasmic reticulum.

The ADAM17 sheddase complex regulator iTAP/Frmd8 modulates inflammation and tumor growth

Marina Badenes, Emma Burbridge, Ioanna Oikonomidi, Abdulbasit Amin, Erika de Carvalho, Lindsay Kosack, Camila Mariano, Pedro Domingos, Pedro Faisca, Colin Adrain

Summary: ADAM17 is a metalloprotease that sheds key molecules, including TNF and epidermal growth factor receptor ligands. It exists within a sheddase complex, including iRhom1 or iRhom2. The protein iTAP/Frmd8 is an iRhom-binding protein that regulates ADAM17 biology. The loss of iTAP/Frmd8 affects inflammatory and intestinal epithelial barrier repair functions, and also regulates cancer cell growth. Targeting iTAP/Frmd8 may be beneficial for specific ADAM17-related diseases, avoiding the collateral impact of widespread ADAM17 inhibition.
