Structure of a melanocyte cell
WebThe structure of melanocyte inducing transcription factor includes three critically important regions. Two of the regions, called the helix-loop-helix motif and the leucine-zipper motif, are critical for protein interactions. WebMelanocyte precursors known as melanoblasts develop from neural crest (NC), a transient structure that emerges from the neuroectoderm under the influence of the notochord during the neurulation process (Dupin et al., 2003; O’Rahilly and Muller, 2007; Young et al., 2009 ).
