Tyrosine Kinase Gene

Using v-abl probes, we have identified and cloned a novel fes/fps-homologous human cDNA, which we have designated FER (pronounced "fair"). This apparently full-length cDNA of 3.0 kilobases has an open reading frame of 2,466 base pairs and the capacity to encode a protein of 94,000 molecular weight. The cDNA contains regions homologous to the highly conserved tyrosine protein kinase domain of other oncogenes and growth factor receptors but lacks a clear transmembrane region, indicating that it encodes a tyrosine kinase of the nonreceptor type. The deduced amino acid sequence of FER resembles that of c-fes/fps. Our data indicate that the protein product of FER, p94FER, corresponds to a previously reported cellular phosphoprotein, NCP94, detected with a v-fps-specific antipeptide antiserum.

Some Ki-1 lymphomas carry a specific chromosomal translocation, t(2;5)(p23;q35). We have recently found a novel hyperphosphorylated 80- kD protein tyrosine kinase, p80, in a human Ki-1 lymphoma with this translocation. Subsequent cDNA cloning showed that p80 is a fusion protein of two different genes on chromosome 2p23 and 5q35, the novel tyrosine kinase gene and nucleophosmin gene, respectively. In this study, we intended to detect p80 on lymphoma tissues with immunologic methods. Thus, we developed rabbit polyclonal antibody using a synthetic peptide corresponding to a part of its kinase domain. The antibody (anti-p80) immunoprecipitated and immunoblotted p80 specifically from AMS3. Then, to examine whether t(2;5)(p23;q35) was present on biopsied lymphomas, reverse transcriptase-polymerase chain reaction (RT-PCR) covering the fusion junction of p80 mRNA was performed. Among 10 Ki-1 lymphomas and 10 additional lymphomas other than the Ki-1 lymphomas, expression of p80 mRNA was detected in three cases exclusively. When these 20 cases and additional 30 lymphomas were immunostained with anti-p80, positive staining was noted exclusively in the three cases found by PCR to have harbored the p80 mRNA. Thus, the present immunostaining, as well as PCR, was shown to be efficient for detecting lymphomas producing this chimeric protein/mRNA.

We used in situ hybridization to study the RNA expression of the dsrc29A gene during Drosophila development. This gene encodes two proteins differing at their amino termini. Both gene products contain a protein-tyrosine kinase domain and resemble the protein encoded by vertebrate src. We examined most stages of development in the Drosophila life cycle: embryos, third instar larvae, pupae and adults. Our results revealed that dsrc29A expression is specialized throughout development, being prominent at various times in neural tissue, phagocytic cells, dorsal vessel, ovaries, gut, developing salivary glands, imaginal discs and disc derivatives. These findings confirm and extend previous results for the distribution of dsrc29A protein, indicating that the regulation of this gene is primarily at the level of transcription. In some tissues expression is transient, whereas in others, it is continuous, and expression occurs in proliferative, differentiating and differentiated tissue. These patterns of expression demonstrate how a single protein-tyrosine kinase might play diverse roles at different times during development. Comparison of the expression of dsrc29A and other members of the protein-tyrosine kinase gene superfamily reveals that the genes are expressed in distinctive but sometimes overlapping patterns.

Abstract The let-23 gene, which encodes a putative tyrosine kinase of the epidermal growth factor (EGF) receptor subfamily, has multiple functions during Caenorhabditis elegans development. We show that let-23 function is required for vulval precursor cells (VPCs) to respond to the signal that induces vulval differentiation: a complete loss of let-23 function results in no induction. However, some let-23 mutations that genetically reduce but do not eliminate let-23 function result in VPCs apparently hypersensitive to inductive signal: as many as five of six VPCs can adopt vulval fates, in contrast to the three that normally do. These results suggest that the let-23 receptor tyrosine kinase controls two opposing pathways, one that stimulates vulval differentiation and another that negatively regulates vulval differentiation. Furthermore, analysis of 16 new let-23 mutations indicates that the let-23 kinase functions in at least five tissues. Since various let-23 mutant phenotypes can be obtained independently, the let-23 gene is likely to have tissue-specific functions.
