Fungal development and the COP9 signalosome.
The conserved COP9 signalosome (CSN) multiprotein complex is located at the interface between cellular signaling, protein modification, life span and the development of multicellular organisms. CSN is required for light-controlled responses in filamentous fungi. This includes the circadian rhythm of Neurospora crassa or the repression of sexual development by light in Aspergillus nidulans. In c...

But what does it really do? This is the $64,000 question. If we must join in the rampant speculation, the CSN probably has multiple functions. It may serve as a master dock, bringing together proteins, such as a kinase, its substrate, and the proteasome. The CSN might even be an alternative or additional proteasome lid, shuttling ubiquitinated substrates from the SCF to the proteasome. Alternat...
متن کاملThe COP9 signalosome.
The COP9 signalosome (CSN) is composed of eight distinct subunits and is highly homologous to the lid sub-complex of the 26S proteasome. CSN was initially defined as a repressor of photomorphogenesis in Arabidopsis, and it has now been found to participate in diverse cellular and developmental processes in various eukaryotic organisms. Recently, CSN was revealed to have a metalloprotease activi...
متن کاملThe COP9 signalosome is essential for development of Drosophila melanogaster
The COP9 signalosome (originally described as the COP9 complex) is an essential multi-subunit repressor of light-regulated development in plants [1] [2]. It has also been identified in mammals, though its role remains obscure [3] [4] [5]. This complex is similar to the regulatory lid of the proteasome and eIF3 [5] [9] [10] [11] [12] and several of its subunits are known to be involved in kinase...
متن کاملJAB1/CSN5 and the COP9 signalosome
The Jun activating binding protein (JAB1) specifically stabilizes complexes of c-Jun or JunD with AP-1 sites, increasing the specificity of target gene activation by AP-1 proteins. JAB1 is also known as COP9 signalosome subunit 5 (CSN5), which is a component of the COP9 signalosome regulatory complex (CSN). Over the past year, JAB1/CSN5 has been implicated in numerous signaling pathways includi...
