Description: MaX-Like: mxl-1 encodes a basic helix-loop-helix protein similar to the vertebrate MAX transcriptional regulators; in vitro, MXL-1 can heterodimerize, and bind an E-box DNA sequence, with MDL-1, a C. elegans MAD-like bHLH protein; mxl-1::gfp reporter fusions are expressed in the posterior intestine and in head and tail neurons.
