The Mr 165,000 M-protein myomesin: a specific protein of cross-striated muscle cells
The tissue specificity of chicken 165,000 M-protein, tentatively names "myomesin", a tightly bound component of the M-line region of adult skeletal and heart myofibrils, was investigated by immunological techniques. Besides skeletal and heart muscle, only thymus (known to contain myogenic cells) was found to contain myomesin. No myomesin could however, be detected in smooth muscle or any other ...
متن کاملBiochemical and ultrastructural aspects of Mr 165,000 M-protein in cross-striated chicken muscle
To better understand the relationship between the Mr 165,000 M-line protein (M-protein) and H-zone structure in skeletal and in cardiac muscle, as well as the possible interaction of M-protein with another skeletal muscle M-line component, the homodimeric creatine kinase isoenzyme composed of two M subunits (MM-CK), we performed biochemical, immunological, and ultrastructural studies on myofibr...
متن کاملMyomesin 3, a novel structural component of the M-band in striated muscle.
The M-band is the cytoskeletal structure that cross-links the myosin and titin filaments in the middle of the sarcomere. Apart from the myosin tails and the C-termini of titin, only two closely related structural proteins had been detected at the M-band so far, myomesin and M-protein. However, electron microscopy studies revealed structural features that do not correlate with the expression of ...
متن کاملMyomesin and M-protein: expression of two M-band proteins in pectoral muscle and heart during development
The expression of the myofibrillar M-band proteins myomesin and M-protein was studied in chicken pectoral muscle and heart during differentiation using monoclonal antibodies in a double-antibody sandwich enzyme-linked immunosorbent assay, immunoblotting, and immunocytochemistry. In presumptive pectoral muscle, myomesin accumulated first, increasing from 2% of the adult concentration at day 7 to...
متن کاملM-caveolin, a muscle-specific caveolin-related protein.
Caveolae, small invaginations of the plasma membrane, are a characteristic feature of many mammalian cells. The best-characterised caveolar protein is the integral membrane protein, VIP21-caveolin. We now describe a novel homologue of VIP21-caveolin, M-caveolin, which is expressed exclusively in muscle. M-caveolin was shown to be expressed in differentiated myotubes but not myoblasts. Epitope-t...
