Anti-MESP1 Antibody Picoband® Fluoro550 Conjugated

Mesoderm posterior 1 homolog (mouse) is a protein that in humans is encoded by the MESP1 gene. It is mapped to 15q26.1. MESP1 is a transcription factor that regulates cardiovascular progenitor specification.The MESP1 gene encodes a member of the basic helix-loop-helix (bHLH) family of transcriptional regulatory proteins that may play a role in the development of nascent mesoderm.

Highly expressed in brain and weakly in heart, small intestine and uterus. Isoform 1A is mostly expressed in granular cell and molecular layer. Isoform 1B is mostly expressed in Purkinje cells. Isoform 1E is predominantly expressed in peripheral tissues as kidney, lung, trachea, colon, small intestine, stomach, bone marrow, thymus and mammary gland. .

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.
