Zinc finger proteins in early Xenopus development.
The C2H2-type zinc finger motif defines a large super family of specific DNA and specific RNA binding proteins. Individual members of this protein family have been demonstrated to carry important regulatory functions in embryogenesis. We have isolated a large collection of C2H2-type zinc finger proteins from Xenopus laevis. Some of these proteins are highly conserved in evolution and found to be differentially expressed during embryonic development of the central nervous system. We also summarize our recent findings on the biochemical characterization of RNA and DNA binding activities in vitro for other Xenopus zinc finger proteins, which fall into structurally defined, distinct subfamilies.
