High impact information on kal-1

  • We have linked individual HS modifications to two specific guidance systems, the sax-3/Robo and kal-1/Anosmin-1 systems, whose activity is dependent on different HS modifications in different cellular contexts [1].
  • In a different cellular context, heterologous C. elegans kal-1 expression causes a highly penetrant axon-misrouting phenotype [2].
  • We also show that kal-1 affects neurite outgrowth in vivo by modulating branching [3].
  • We show that kal-1 is part of a mechanism by which neurons influence migration and adhesion of epidermal cells undergoing morphogenesis during ventral enclosure and male tail formation [3].
