Down-regulation of c-Fos/c-Jun AP-1 dimer activity by sumoylation.
The inducible transcriptional complex AP-1, composed of c-Fos and c-Jun proteins, is crucial for cell adaptation to many environmental changes. While its mechanisms of activation have been extensively studied, how its activity is restrained is poorly understood. We report here that lysine 265 of c-Fos is conjugated by the peptidic posttranslational modifiers SUMO-1, SUMO-2, and SUMO-3 and that ...
متن کاملRegulation of pokemon 1 activity by sumoylation.
Pokemon 1 is a proto-oncogenic transcriptional regulator that contains a POZ domain at the N-terminus and four Kruppel-like zinc fingers at the C-terminus. Pokemon 1 plays an important role in adipogenesis, osteogenesis, oncogenesis, and transcription of NF-kB responsive genes. Recent reports have shown that biological activities of transcription factors are regulated by sumolylation. We invest...
متن کاملMAX-1, a Novel PH/MyTH4/FERM Domain Cytoplasmic Protein Implicated in Netrin-Mediated Axon Repulsion
The netrin UNC-6 repels motor axons by activating the UNC-5 receptor alone or in combination with the UNC-40/DCC receptor. In a genetic screen for C. elegans mutants exhibiting partial defects in motor axon projections, we isolated the max-1 gene (required for motor neuron axon guidance). max-1 loss-of-function mutations cause fully penetrant but variable axon guidance defects. Mutations in unc...
متن کاملMolecular analysis of axon repulsion by the notochord.
During development of the amniote peripheral nervous system, the initial trajectory of primary sensory axons is determined largely by the action of axon repellents. We have shown previously that tissues flanking dorsal root ganglia, the notochord lying medially and the dermamyotomes lying laterally, are sources of secreted molecules that prevent axons from entering inappropriate territories. Al...
متن کاملAxon repulsion during peripheral nerve segmentation.
The guidance of axons during embryonic development is likely to involve both adhesive and repulsive interactions between growth cones and their environment. We are characterising the role and mechanism of repulsion during the segmental outgrowth of motor and sensory axons in the somite mesoderm of chick embryos. Axons are confined to the anterior half of each somite by the expression in the pos...
