The molecular complexes containing BCL10, MALT1 and CARMA proteins (CBM complex) have been recently identified as a key component in the signal transduction pathways that regulate activation of Nuclear Factor kappaB (NF-κB) transcription factor. Herein we identified the DEP domain-containing protein DEPDC7 as cellular binding partners of CARMA2 and CARMA3 proteins. DEPDC7 displays a cytosolic distribution and its expression induces NF-κB activation. Conversely, shRNA-mediated abrogation of DEPDC7 results in impaired NF-κB activation following G protein-coupled receptors stimulation, or stimuli that require CARMA2 and CARMA3, but not CARMA1. Thus, this study identifies DEPDC7 as a CARMA interacting molecule, and provides evidence that DEPDC7 may be required to specifically convey on the CBM complex signals coming from activated G protein-coupled receptors. © 2014 D9 Andrea et al.

Initially identified by their ability to modulate the functional activity of BCL10, the three CARMA proteins, CARMA1, -2, and -3, have recently themselves taken a leading role on the stage of molecular medicine. Although considered for some time as simple ancillary proteins, increasingly accumulating recent data evidently indicate a role of primary importance for these three proteins in the pathophysiology of several human tumors and inflammatory disorders. In fact, recent scientific literature clearly establishes that CARMA1 is one of the most mutated genes in a subtype of B-cell lymphoma and, at the same time, responsible for some rare human immunodeficiency conditions. On the other hand, mutations in CARMA2 are responsible for the hereditary transmission of some inflammatory disorders of the skin, including familial psoriasis and ptiriasis; whereas expression of CARMA3 appears to be deregulated in different human tumors. Here we describe and summarize the mutations found in the genes coding for the three CARMA proteins in these different human pathological conditions, and offer an interpretation of the molecular mechanisms from which arise the biological outcomes in which these proteins are involved. © 2013 Wiley Periodicals, Inc.

The I-κB kinase (IKK) subunit NEMO/IKKoγ (NEMO) is an adapter molecule that is critical for canonical activation of NF-κB, a pleiotropic transcription factor controlling immunity, differentiation, cell growth, tumorigenesis, and apoptosis. To explore the functional role of canonical NF-κB signaling in thyroid gland differentiation and function, we have generated a murine strain bearing a genetic deletion of the NEMO locus in thyroid. Here we show that thyrocyte-specific NEMO knock-out mice gradually develop hypothyroidism after birth, which leads to reduced body weight and shortened life span. Histological and molecular analysis indicate that absence of NEMO in thyrocytes results in a dramatic loss of the thyroid gland cellularity, associated with down-regulation of thyroid differentiation markers and ongoing apoptosis. Thus, NEMO-dependent signaling is essential for normal thyroid physiology. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

The seven members of the tumor necrosis factor receptor (TNF-R)-associated factor (TRAF) family of intracellular proteins were originally discovered and characterized as signaling adaptor molecules coupled to the cytoplasmic regions of receptors of the TNF-R superfamily. Functionally, TRAFs act both as a scaffold and/or enzymatic proteins to regulate activation of mitogen-activated protein kinases (MAPKs) and transcription factors of nuclear factor-B family (NF-B). Given the wide variety of stimuli intracellularly conveyed by TRAF proteins, they are physiologically involved in multiple biological processes, including embryonic development, tissue homeostasis and regulation of innate and adaptive immune responses. In the last few years, it has become increasingly evident the involvement of TRAF7, the last member of the TRAF family to be discovered, in the genesis and progression of several human cancers, placing TRAF7 in the spotlight as a novel tumor suppressor protein. In this paper, we review and discuss the literature recently produced on this subject. This article is protected by copyright. All rights reserved.
