'''Crystal structure of the C-terminal domain of mouse Nrdp1'''<br />


==Overview==
==Crystal structure of the C-terminal domain of mouse Nrdp1==
The E3 ubiquitin ligase neuregulin receptor degrading protein 1 (Nrdp1), mediates the ligand-independent degradation of the epidermal growth factor, receptor family member ErbB3/HER3. By regulating cellular levels of ErbB3, Nrdp1 influences ErbB3-mediated signaling, which is essential for normal, vertebrate development. Nrdp1 belongs to the tripartite or RBCC (RING, B-box, coiled-coil) family of ubiquitin ligases in which the RING domain, is responsible for ubiquitin ligation and a variable C-terminal region, mediates substrate recognition. We report here the 1.95 A crystal, structure of the C-terminal domain of Nrdp1 and show that this domain is, sufficient to mediate ErbB3 binding. Furthermore, we have used, site-directed mutagenesis to map regions of the Nrdp1 surface that are, important for interacting with ErbB3 and mediating its degradation in, transfected cells. The ErbB3-binding site localizes to a region of Nrdp1, that is conserved from invertebrates to vertebrates, in contrast to ErbB3, which is only found in vertebrates. This observation suggests that Nrdp1, uses a common binding site to recognize its targets in different species.

== Function ==
[https://www.uniprot.org/uniprot/RNF41_MOUSE RNF41_MOUSE] Acts as E3 ubiquitin-protein ligase and regulates the degradation of target proteins. Contributes to the maintenance of steady-state ERBB3 levels by mediating its growth factor-independent degradation. Involved in the degradation of the inhibitor of apoptosis BIRC6 and thus is an important regulator of cell death by promoting apoptosis. Acts also as a PARK2 modifier that accelerates its degradation, resulting in a reduction of PARK2 activity, influencing the balance of intracellular redox state. Polyubiquitinates MYD88 (By similarity). Negatively regulates MYD88-dependent production of proinflammatory cytokines but can promote TRIF-dependent production of type I interferon and inhibits infection with vesicular stomatitis virus. Promotes also activation of TBK1 and IRF3. Involved in the ubiquitination of erythropoietin (EPO) and interleukin-3 (IL-3) receptors. Thus, through maintaining basal levels of cytokine receptors, FLRF is involved in the control of hematopoietic progenitor cell differentiation into myeloerythroid lineages.<ref>PMID:18495327</ref> <ref>PMID:19483718</ref>

The E3 ubiquitin ligase neuregulin receptor degrading protein 1 (Nrdp1) mediates the ligand-independent degradation of the epidermal growth factor receptor family member ErbB3/HER3. By regulating cellular levels of ErbB3, Nrdp1 influences ErbB3-mediated signaling, which is essential for normal vertebrate development. Nrdp1 belongs to the tripartite or RBCC (RING, B-box, coiled-coil) family of ubiquitin ligases in which the RING domain is responsible for ubiquitin ligation and a variable C-terminal region mediates substrate recognition. We report here the 1.95 A crystal structure of the C-terminal domain of Nrdp1 and show that this domain is sufficient to mediate ErbB3 binding. Furthermore, we have used site-directed mutagenesis to map regions of the Nrdp1 surface that are important for interacting with ErbB3 and mediating its degradation in transfected cells. The ErbB3-binding site localizes to a region of Nrdp1 that is conserved from invertebrates to vertebrates, in contrast to ErbB3, which is only found in vertebrates. This observation suggests that Nrdp1 uses a common binding site to recognize its targets in different species.
