Transgelin/TAGLN: Proteins and Enzymes

In contrast to fast and slow skeletal muscle cells that fuse and terminally differentiate, smooth muscle cells are able to simultaneously proliferate and express lineage-restricted proteins. One of these proteins, expressed exclusively in smooth muscles, has been referred to as SM22-alpha, a 22 kDa protein with structural similarity to the vertebrate thin filament myofibrillar regulatory protein calponin and the Drosophila muscle protein mp20, neither of which play a direct role in the ...
