Glial cells play fundamental roles in neurogenesis. In addition, defective
or abnormal gliogenesis is associated with severe diseases. To understand t
he molecular basis of such diseases, it is crucial to identify the genes pr
omoting normal gliogenesis. Here we identify GCMB, which encodes a human pr
otein homologous to the fly glial promoting factor glial cell deficient/gli
al cell missing (glide/gcm).
