Function

E3 ubiquitin ligase catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins (PubMed:12496252, PubMed:17675297, PubMed:29883609, PubMed:30952868). Involved in the TLR and IL-1 signaling pathways via interaction with the complex containing IRAK kinases and TRAF6 (PubMed:12496252, PubMed:17675297). Acts as a positive regulator of inflammatory response in microglia through activation of NF-kappa-B and MAP kinase (By similarity). Mediates 'Lys-63'-linked polyubiquitination of IRAK1 allowing subsequent NF-kappa-B activation (PubMed:12496252, PubMed:17675297). Conjugates 'Lys-63'-linked ubiquitin chains to the adapter protein ASC/PYCARD, which in turn is crucial for NLRP3 inflammasome activation (PubMed:34706239). Mediates 'Lys-48'-linked polyubiquitination of RIPK3 leading to its subsequent proteasome-dependent degradation; preferentially recognizes and mediates the degradation of the 'Thr-182' phosphorylated form of RIPK3 (PubMed:29883609). Negatively regulates necroptosis by reducing RIPK3 expression (PubMed:29883609). Mediates 'Lys-63'-linked ubiquitination of RIPK1 (PubMed:29883609). Following phosphorylation by ATM, catalyzes 'Lys-63'-linked ubiquitination of NBN, promoting DNA repair via homologous recombination (PubMed:30952868). Negatively regulates activation of the metabolic mTORC1 signaling pathway by mediating 'Lys-63'-linked ubiquitination of mTORC1-inhibitory protein TSC1 and thereby promoting TSC1/TSC2 complex stability (PubMed:33215753).

Activity summary

Pellino 1 and Pellino 2 are E3 ubiquitin ligases known for their roles in mediating immune responses. Alternate names for Pellino proteins include PEK and PELI. Pellino 1 has a molecular mass of approximately 47 kDa while Pellino 2 has a mass around 45 kDa. These proteins localize mainly in the cytoplasm and nucleus of immune cells such as macrophages and dendritic cells. They participate in transmitting signals from receptors to downstream signaling proteins essential for regulating immune pathways.

Biological function summary

These proteins play significant roles in controlling the TLR/IL-1 signaling pathway. Pellino 1 and Pellino 2 can form complexes with other signaling intermediates like IRAK1 and TRAF6 which are key components in innate immunity. They add ubiquitin molecules to specific target proteins thereby modulating their stability and activity. This ubiquitination process is important in facilitating the proper response to infections.

Pathways

Pellino 1 and Pellino 2 are integral to the NF-kB and MAPK signaling pathways both of which are central to immune response regulation. They interact with proteins like IRAK1 to promote activation of these pathways leading to gene expression necessary for inflammation and defense mechanisms. This regulation ensures that cells mount an appropriate immune response against pathogens and maintain homeostasis.

Associated diseases and disorders

Impaired function or regulation of Pellino proteins links to autoimmune diseases such as rheumatoid arthritis and inflammatory disorders like Crohn’s disease. These conditions involve inappropriate activation of immune pathways where increased Pellino activity can exacerbate inflammatory responses. Pellino proteins connect with TNF-alpha a cytokine prominent in these disorders highlighting their critical roles in disease modulation.
