A myosin-like protein from smooth muscle.
A protein was purified from chicken gizzard smooth muscle. It bound ATP and actin. Actin activated the Mg2(+)-ATPase activity of this protein. The Ca2(+)-ATPase activity was lower than K(+)-EDTA ATPase activity. Thus, it appears that this protein is akin to myosin I rather than to conventional myosin. However, ATPase activities of the protein were much lower than those of myosin I. A protein co...
متن کاملPlatelet membranes induce airway smooth muscle cell proliferation.
The role of platelets in airway disease is poorly understood although they have been suggested to influence on proliferation of airway smooth muscle cells (ASMC). Platelets have been found localized in the airways in autopsy material from asthmatic patients and have been implicated in airway remodeling. The aim of the present study was to investigate the effects of various platelet fractions on...
متن کاملDemonstration of adenosine receptors on mouse cerebral smooth muscle membranes.
Adenosine receptors have been identified on brain cortical membranes and microvascular preparations. However, they have not been demonstrated on specific microvascular elements in isolation. 2-3H-chloroadenosine was used as a ligand to investigate the presence of adenosine receptors on isolated mouse cerebral smooth muscle membranes. The binding studies reveal the presence of a high affinity bi...
متن کاملAssessing the Nature of Lipid Raft Membranes
The paradigm of biological membranes has recently gone through a major update. Instead of being fluid and homogeneous, recent studies suggest that membranes are characterized by transient domains with varying fluidity. In particular, a number of experimental studies have revealed the existence of highly ordered lateral domains rich in sphingomyelin and cholesterol (CHOL). These domains, called ...
متن کاملDetection of submicron-sized raft-like domains in membranes by small-angle neutron scattering.
Using coarse grained models of heterogeneous vesicles we demonstrate the potential for small-angle neutron scattering (SANS) to detect and distinguish between two different categories of lateral segregation: 1) unilamellar vesicles (ULV) containing a single domain and 2) the formation of several small domains or "clusters" (approximately 10 nm in radius) on a ULV. Exploiting the unique sensitiv...
