High impact information on Isl2

  • We have cloned a family of LIM homeobox genes in chick and show here that the combinatorial expression of four of these genes, Islet-1, Islet-2, Lim-1, and Lim-3, defines subclasses of motor neurons that segregate into columns in the spinal cord and select distinct axonal pathways [1].
  • We find that activated RARbeta up-regulates islet-1 expression, whereas activation of RARalpha can either act in combination with RARbeta signalling to maintain islet-1 expression or induce islet-2 expression in the absence of activated RARbeta [2].
