Example sentences for: caldesmon
How can you use “caldesmon” in a sentence? Here are some example sentences to help you improve your vocabulary:
The high molecular weight caldesmon (h-caldesmon) is the major isoform of intact vascular smooth muscle [ 7 ] . On the Western blots h-caldesmon appeared as a single band with apparent molecular weight of 130 kDa, which comigrated with h-caldesmon standard, purified from porcine stomach [ 8 ] . Densitometry of immunoreactive bands revealed that the artery contained approximately 1.39 times more h-caldesmon than vein (Fig.
It remains to be determined whether the relatively bigger amount of caldesmon and TM-α is advantageous for the artery in fulfilling resistive functions, and whether more TM-β is a prerequisite for veins to fulfill capacitative functions in the mesenteric circulation.
We assayed the contents of some thin filament binding proteins, proposed to play roles in modulation of the actin-myosin coupling, e.g. calponin, caldesmon, and TM.
Caldesmon is likely to play a modulatory role on the production of smooth muscle force via a tethering of actin to myosin [ 11 ] and/or of its effects on the actomyosin ATPase [ 12 13 14 ] . Similarly, TM does not seem to function as a major regulatory protein, but modulatory effects due to its ability to maintain the actin filamentous structure [ 15 ] , to inhibit the Ca 2+-ATPase activity [ 16 ] , alter the cytoskeletal dynamics [ 17 ] and improve actin filament flexibility during the contraction/relaxation cycle [ 18 19 ] have been well documented.
For example, phasic and tonic behavior of gastrointestinal smooth muscles has been attributed to different expression levels of caldesmon and caldesmon-binding proteins, but not to differences in the relative proportions of myosin, actin, calponin, and tropomyosin [ 1 2 ] . Arteries and veins of different vascular beds are primarily composed of tonic smooth muscles.
