SysZNF: the C2H2 zinc finger gene database

G. Ding, P. Lorenz, M. Kreutzer, Y. Li, H.-J. Thiesen
2009 Nucleic Acids Research  
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.  ...  Here, we systematically collected all the C2H2-ZNF genes in the human and mouse genome and constructed a database named SysZNF to deposit available datasets related to these genes.  ...  Defined C2H2-ZNF motifs have been applied to engineer custom zinc-finger nucleases (ZFN) for gene therapy (11) .  ...

A common mode of recognition for methylated CpG

Yiwei Liu, Xing Zhang, Robert M. Blumenthal, Xiaodong Cheng
2013 TIBS -Trends in Biochemical Sciences. Regular ed  
Two recent structures of C2H2 zinc finger (ZnF) proteins in complex with methylated DNA reveal a common recognition mode for 5-methylcytosine (5mC) that involves a 5mC-Arg-G triad.  ...  We propose that the RH-ZnF motifs provide specificity for 5mCpG, whereas the neighboring Zn fingers recognize the surrounding DNA sequence context.  ...  The C2H2 Zinc Finger Gene database (SysZNF) was searched for ZnFs containing RH motifs at the proper position [39] .  ...

Re-programming DNA-binding specificity in zinc finger proteins for targeting unique address in a genome

Abhinav Grover, Akshay Pande, Krishna Choudhary, Kriti Gupta, Durai Sundar
2010 Journal of Systems and Synthetic Biology  
Here, we explore the novel functionality obtained by engineered zinc finger proteins and the computational approaches for prediction of recognition helices of zinc finger proteins that can raise our ability  ...  Custom-design of zinc finger proteins with tailor-made specificity is currently limited by the availability of information on recognition helices for all possible DNA targets.  ...  the IYBA scheme.  ...

2010 BMC Genomics  
Expansion of multi-C2H2 domain zinc finger (ZNF) genes, including the Krüppel-associated box (KRAB) subfamily, paralleled the evolution of tetrapodes, particularly in mammalian lineages.  ...  The analysis of orthologs in therian mammalian species revealed strong conservation and purifying selection of the KRAB-A and zinc finger domains.  ...  We are grateful to all colleagues that provided the scientific community with freely available software tools and databases.  ...

A New Family of Predicted Krüppel-Like Factor Genes and Pseudogenes in Placental Mammals

Jimin Pei, Nick V. Grishin, Eugene Yujun Xu
2013 PLoS ONE  
Predicted KLF18 proteins maintain conserved features in the zinc fingers of the SP/KLF family, while possessing repeats of a unique sequence motif in their N-terminal regions.  ...  Krüppel-like factors (KLF) and specificity proteins (SP) constitute a family of zinc-finger-containing transcription factors that play important roles in a wide range of processes including differentiation  ...  Acknowledgements We would like to thank Lisa Kinch for critical reading of the manuscript.
