| abstractText | We have isolated cDNAs representing multiple members of murine groucho homologues, designated Grg for groucho-related genes. Among them, Grg3 appears to produce two transcripts. One of the Grg3 transcripts contains coding sequence for a complete Groucho protein homologue. The second transcript contains coding sequence for only the two amino-terminal domains of the Groucho protein, followed by a hydrophobic tail and a stop codon. We analyzed the expression of both transcripts in mouse embryos using RNase protection and in situ hybridization. Expression was detected during cell determination in the nervous system and in somitic mesoderm, overlapping Notch1 expression and adjacent to Mash1, MyoD and Myf5 expression. Thus, the expression pattern of Grg3 suggests a conserved role in the Notch signalling pathway to regulate expression of basic helix-loop-helix proteins and cell determination. Grg3 expression was also consistently detected in epithelial structures undergoing mesenchyme induction. |
