Abstract excerpt
Islet-1 (Isl1) is a member of the Isl1 family of LIM-homeodomain transcription factors (LIM-HD) that is expressed in a defined subset of motor and sensory neurons during vertebrate embryogenesis. To investigate how this specific expression of isl1 is regulated, we searched for enhancers of the isl1 gene that are conserved in vertebrate evolution. Initially, two enhancer elements, CREST1 and CREST2, were...
