Our aim was to identify new human proteins with potential DNA binding activity, related to the Krüppel protein which regulates Drosophila segmentation. We screened a human placenta cDNA library and a human genomic DNA library with a synthetic oligonucleotide probe corresponding to the H/C link region that connects finger loops in the multifingered Krüppel protein. We found more than 100 different mRNAs encoding Krüppel multifingered proteins in the human placenta. In the whole human genome, the number of genes encoding such proteins reaches about 300. Sequence analysis of 14 cloned cDNAs indicated that they code for at least nine undescribed human finger proteins. The sequences of the 106 finger repeats present in these nine proteins are highly homologous. Most of the variability lies in a limited number of positions located in their postulated alpha-helical structure, and therefore could be implicated in their DNA-binding specificity.

Protein involved in the transfer of genetic information from DNA to messenger RNA (mRNA) by DNA-directed RNA polymerase. In the case of some RNA viruses, protein involved in the transfer of genetic information from RNA to messenger RNA (mRNA) by RNA-directed RNA polymerase.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
