MLC-2A

A myosin specific for the atrium of the mammalian heart

General Information

During cardiogenesis two major isoforms of myosin light chain 2 are co-expressed in a tightly regulated manner. MLC-2A is only present in the atrium while MLC-2V is exclusively expressed in the ventricle. Knock out studies revealed that the 2A isoform cannot substitute for the 2V variant in the ventricular chamber.
Recently it has been demonstrated that embryonic and adult stem cells can be differentiated into cardiomyocytes which may generate suitable replacements for damaged heart tissue in the future.
This monoclonal antibody is a useful tool to distinguish between ventricle and atrium specific cardiomyocytes.
