Ring finger motif of Arabidopsis thaliana COP1 defines a new class of zinc-binding domain.
The COP1 gene of Arabidopsis thaliana encodes a protein mediating the switch between the two developmental pathways utilized in light and darkness. A cysteine-rich motif identified the COP1 protein as a member of a group of regulatory proteins which share the amino acid motif Cys-X-X-Cys-loop I-Cys-X-His-X-X-Cys-X-X-Cys-loop II-Cys-X-X-Cys (ring finger). Although this new class of cysteine-rich...
متن کاملThe RING finger motif of photomorphogenic repressor COP1 specifically interacts with the RING-H2 motif of a novel Arabidopsis protein.
The constitutive photomorphogenic 1 (COP1) protein of Arabidopsis functions as a molecular switch for the seedling developmental fates: photomorphogenesis under light conditions and skotomorphogenesis in darkness. The COP1 protein contains a cysteine-rich zinc-binding RING finger motif found in diverse groups of regulatory proteins. To understand the role of the COP1 RING finger in mediating pr...
متن کاملThe LIM motif defines a specific zinc-binding protein domain.
The cysteine-rich protein (CRP) contains two copies of the LIM sequence motif, CX2CX17HX2CX2CX2CX17-CX2C, that was first identified in the homeodomain proteins Lin-11, Is1-1, and Mec-3. The abundance and spacing of the cysteine residues in the LIM motif are reminiscent of a metal-binding domain. We examined the metal-binding properties of CRP isolated from chicken smooth muscle (cCRP) and from ...
متن کاملNMR structure of the single QALGGH zinc finger domain from the Arabidopsis thaliana SUPERMAN protein.
Zinc finger domains of the classical type represent the most abundant DNA binding domains in eukaryotic transcription factors. Plant proteins contain from one to four zinc finger domains, which are characterized by high conservation of the sequence QALGGH, shown to be critical for DNA-binding activity. The Arabidopsis thaliana SUPERMAN protein, which contains a single QALGGH zinc finger, is nec...
متن کاملTreble clef finger--a functionally diverse zinc-binding structural motif.
Detection of similarity is particularly difficult for small proteins and thus connections between many of them remain unnoticed. Structure and sequence analysis of several metal-binding proteins reveals unexpected similarities in structural domains classified as different protein folds in SCOP and suggests unification of seven folds that belong to two protein classes. The common motif, termed t...
