Abstract:
AbstractIn order to demonstrate that an existing zinc-finger protein can be simply modified to enhance DNA binding and sequence discrimination in both episomal and chromatin contexts using existing zinc-finger DNA recognition code data, and without recourse to phage display and selection strategies, we have examined the consequences of a single zinc-finger extension to a synthetic three-zinc-finger VP16 fusion protein, on transcriptional activation from model target promoters harbouring the zinc-finger binding sequences. We report a nearly 10-fold enhanced transcriptional activation by the fou

Abstract:
The zinc finger proteins make up a significant part of the proteome and perform a huge variety of functions in the cell. The CCCH-type zinc finger proteins have gained attention due to their unusual ability to interact with RNA and thereby control different steps of RNA metabolism. Since virus infections interfere with RNA metabolism, dynamic changes in the CCCH-type zinc finger proteins and virus replication are expected to happen. In the present review, we will discuss how three CCCH-type zinc finger proteins, ZC3H11A, MKRN1, and U2AF1, interfere with human adenovirus replication. We will su

Abstract:
Three-finger proteins (TFPs) are small proteins with characteristic three-finger β-structural fold stabilized by the system of conserved disulfide bonds. These proteins have been found in organisms from different taxonomic groups and perform various important regulatory functions or act as components of snake venoms. Recently, four TFPs (Lystars 1–4) with unknown function were identified in the coelomic fluid proteome of starfish A. rubens. Here we analyzed the genomes of A. rubens and A. planci starfishes and predicted additional five and six proteins containing three-finger domains, respecti

Abstract:
Three-finger proteins (TFPs), or Ly6/uPAR proteins, are characterized by the beta-structural LU domain containing three protruding “fingers” and stabilized by four conserved disulfide bonds. TFPs were initially characterized as snake alpha-neurotoxins, but later many studies showed their regulatory roles in different organisms. Despite a known expression of TFPs in vertebrates, they are poorly studied in other taxa. The presence of TFPs in starfish was previously shown, but their targets and functional role still remain unknown. Here, we analyzed expression, target, and possible function of th

Abstract:
The plant homeodomain finger (PHD finger) protein, a type of zinc finger protein extensively distributed in eukaryotes, plays diverse roles in regulating plant growth and development. While PHD finger proteins have been identified in various species, their functions remain largely unexplored in pea (Pisum sativum). In this study, we identified 84 members of the PHD finger gene family in pea, which displayed an uneven distribution across seven chromosomes. Through a comprehensive analysis using data from Arabidopsis thaliana and Medicago truncatula, we categorized the PHD finger proteins into 2

<p>Krüppel-related zinc finger proteins constitute the largest single class of transcription factors within the human genome. Members of this protein family have the ability to either activate or repress transcription depending on the presence of specific activator or repressor domains within the protein. Approximately one third of the Krüppel-related zinc finger proteins contain an evolutionarily well-conserved repressor domain termed the KRAB domain. This domain acts as a potent repressor of transcription by interacting with the co-repressor protein, TIF1β. TIF1β then, in turn, recruits HP1

DGK consists of a number of isozymes with different enzymological properties.

Despite structural similarities these isozymes are expressed markedly differently, depending on the cell types.

Abstract Tricho-rhino-phalangeal syndromes (TRPSs) is an autosomal dominant malformation syndrome which is characterized by craniofacial and skeletal abnormalities. The main features of all three subtypes, TRPS I, II, and III, are caused by mutations in or deletions of the TRPS1 gene on human chromosome 8. TRPS1 encodes a protein featuring an unusual combination of different zinc finger motifs, including GATA-type and IKAROS-like domains. The protein is a potent repressor of GATA-mediated gene expression.

Plants are sessile organisms and, therefore, amicable to various stress conditions, and in order, they produce various secondary metabolites as a defence mechanism. Plants‘ secondary metabolites were classified into three major classes: Phenolics, terpenoids and nitrogen- containing compounds, including alkaloids. In this review, we start with a general introduction to the different pathways producing significant classes of secondary metabolites in plants. We also discuss recent literature producing representatives of plant secondary metabolite classes in heterologous hosts by tissue culture.
