A Drosophila homolog of human proto-oncogene ret transiently expressed in embryonic neuronal precursor cells including neuroblasts and CNS cells.

abstract：:The products of the trithorax gene are required to stably maintain homeotic gene expression patterns established during embryo-genesis by the action of the transiently expressed segmentation genes. We have determined the intron/exon structure of the trx gene and the large alternatively spliced trx RNAs, which are capa...
