Crystal Structure of Ripk4 Reveals Dimerization-Dependent Kinase Activity.
Structure, 26:767-, 2018

PubMed Abstract: Receptor-interacting protein kinase 4 (RIPK4) is a highly conserved regulator of epidermal differentiation. Members of the RIPK family possess a common kinase domain as well as unique accessory domains that likely dictate subcellular localization and substrate preferences. Mutations in human RIPK4 manifest as Bartsocas-Papas syndrome (BPS), a genetic disorder characterized by severe craniofacial and limb abnormalities. We describe the structure of the murine Ripk4 (MmRipk4) kinase domain, in ATP- and inhibitor-bound forms. The crystallographic dimer of MmRipk4 is similar to those of RIPK2 and BRAF, and we show that the intact dimeric entity is required for MmRipk4 catalytic activity through a series of engineered mutations and cell-based assays. We also assess the impact of BPS mutations on protein structure and activity to elucidate the molecular origins of the disease.
