LC3C, Bound Selectively by a Noncanonical LIR Motif in NDP52, Is Required for Antibacterial Autophagy
Autophagy protects cellular homeostasis by capturing cytosolic components and invading pathogens for lysosomal degradation. Autophagy receptors target cargo to autophagy by binding ATG8 on autophagosomal membranes. The expansion of the ATG8 family in higher eukaryotes suggests that specific interactions with autophagy receptors facilitate differential cargo handling. However, selective interact...
متن کاملiLIR@viral: A web resource for LIR motif-containing proteins in viruses
Macroautophagy/autophagy has been shown to mediate the selective lysosomal degradation of pathogenic bacteria and viruses (xenophagy), and to contribute to the activation of innate and adaptative immune responses. Autophagy can serve as an antiviral defense mechanism but also as a proviral process during infection. Atg8-family proteins play a central role in the autophagy process due to their a...
متن کاملThe IQ Motif is Crucial for Cav1.1 Function
Ca(2+)-dependent modulation via calmodulin, with consensus CaM-binding IQ motif playing a key role, has been documented for most high-voltage-activated Ca(2+) channels. The skeletal muscle Ca(v)1.1 also exhibits Ca(2+)-/CaM-dependent modulation. Here, whole-cell Ca(2+) current, Ca(2+) transient, and maximal, immobilization-resistant charge movement (Q(max)) recordings were obtained from culture...
متن کاملSelective autophagy.
During the last decade it has become evident that autophagy is not simply a non-selective bulk degradation pathway for intracellular components. On the contrary, the discovery and characterization of autophagy receptors which target specific cargo for lysosomal degradation by interaction with ATG8 (autophagy-related protein 8)/LC3 (light-chain 3) has accelerated our understanding of selective a...
متن کاملiLIR database: A web resource for LIR motif-containing proteins in eukaryotes
Atg8-family proteins are the best-studied proteins of the core autophagic machinery. They are essential for the elongation and closure of the phagophore into a proper autophagosome. Moreover, Atg8-family proteins are associated with the phagophore from the initiation of the autophagic process to, or just prior to, the fusion between autophagosomes with lysosomes. In addition to their implicatio...
