[[http://www.uniprot.org/uniprot/SKP1A_ARATH SKP1A_ARATH]] Involved in ubiquitination and subsequent proteasomal degradation of target proteins. Together with CUL1, RBX1 and a F-box protein, it forms a SCF E3 ubiquitin ligase complex. The functional specificity of this complex depends of the type of F-box protein. In the SCF complex, it serves as an adapter that links the F-box protein to CUL1. SCF(UFO) is required for vegetative and floral organ development as well as for male gametogenesis. SCF(TIR1) is involved in auxin signaling pathway. SCF(COI1) regulates responses to jasmonates. SCF(EID1) and SCF(AFR) are implicated in phytochrome A light signaling. SCF(ADO1), SCF(ADO2), SCF(ADO3) are related to the circadian clock. SCF(ORE9) seems to be involved in senescence. SCF(EBF1/EBF2) may regulate ethylene signaling. Plays a role during embryogenesis and early postembryonic development, especially during cell elongation and division. Contributes to the correct chromosome segregation during tetrad formation.<ref>PMID:10528262</ref> <ref>PMID:10398681</ref> <ref>PMID:10500191</ref> <ref>PMID:11526079</ref> <ref>PMID:12970487</ref> <ref>PMID:14688296</ref> [[http://www.uniprot.org/uniprot/COI1_ARATH COI1_ARATH]] Required for jasmonate-regulated plant fertility and defense processes, and for coronatine and/or other elicitors perceptions/responses. Seems to not be required for meiosis. Required for the regulation of some genes induced by wounding, but not for all. Component of SCF(COI1) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (probably including the ribulose bisphosphate carboxylase small chain 1B RBCS-1B and the histone deacetylase HDA6). These SCF complexes play crucial roles in regulating response to jasmonate, and their interactions with the COP9 signalosome (CSN) appear to be important for their activity. Interacts with TIFY10A and inositol pentakisphosphate to form a high-affinity jasmonates coreceptor. Involved in the regulation of plant gene expression during plant-pathogen interactions with Pseudomonas syringae and Alternaria brassicicola.<ref>PMID:9582125</ref> <ref>PMID:12244256</ref> <ref>PMID:10810145</ref> <ref>PMID:12172836</ref> <ref>PMID:12172031</ref> <ref>PMID:12445118</ref> <ref>PMID:12724535</ref> <ref>PMID:12805591</ref> <ref>PMID:14756769</ref> | |||
