MESP1 (Mesoderm Posterior BHLH Transcription Factor 1) is a Protein Coding gene. Among its related pathways are Cardiac Progenitor Differentiation. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and protein dimerization activity. An important paralog of this gene is MESP2. Transcription factor. Plays a role in the epithelialization of somitic mesoderm and in the development of cardiac mesoderm. Defines the rostrocaudal patterning of the somites by participating in distinct Notch pathways (By similarity).
