C2H2 zinc finger-SET histone methyltransferase is a plant-specific chromatin modifier.
Histone modification represents a universal mechanism for regulation of eukaryotic gene expression underlying diverse biological processes from neuronal gene expression in mammals to control of flowering in plants. In animal cells, these chromatin modifications are effected by well-defined multiprotein complexes containing specific histone-modifying activities. In plants, information about the ...
متن کاملSpecific RNA binding by a single C2H2 zinc finger.
Zinc finger proteins with high affinity for human immunodeficiency virus Rev responsive element stem loop IIB (RRE-IIB) were previously isolated from a phage display zinc finger library. Zinc fingers from one of these proteins, RR1, were expressed individually and assayed for RRE-IIB affinity. The C-terminal zinc finger retained much of the binding affinity of the two-finger parent and was disr...
متن کاملSysZNF: the C2H2 zinc finger gene database
C2H2 zinc finger (C2H2-ZNF) genes are one of the largest and most complex gene super-families in metazoan genomes, with hundreds of members in the human and mouse genome. The ongoing investigation of this huge gene family requires computational support to catalog genotype phenotype comparisons of C2H2-ZNF genes between related species and finally to extend the worldwide knowledge on the evoluti...
متن کاملSelective dimerization of a C2H2 zinc finger subfamily.
The C2H2 zinc finger is the most prevalent protein motif in the mammalian proteome. Two C2H2 fingers in Ikaros are dedicated to homotypic interactions between family members. We show here that these fingers comprise a bona fide dimerization domain. Dimerization is highly selective, however, as homologous domains from the TRPS-1 and Drosophila Hunchback proteins support homodimerization, but not...
متن کاملA mitochondrial origin for eukaryotic C2H2 zinc finger regulators?
1 discussed the phylogenetic distribution of C2H2 zinc finger transcriptional regulators, which were thought to be exclusively eukaryotic but have been recently found in several prokaryotes. These proteins display different regulatory roles in Sphingomonas aromaticivorans and some members of the symbiotic bacterial genera Rhizobium, Sinorhizobium and Agrobacterium. Distantly related proteins ha...
