WebJan 26, 2011 · Spine actin dynamics maintain synapse structure and function, and cytoskeletal rearrangements in these structures trigger structural and functional plasticity. Therefore, proteins that interact with actin filaments are attractive candidates to regulate synaptic actin dynamics and, thus, synapse structure and function. WebActin filaments in the spine head are very dynamic and show a high turnover by continuous treadmilling (Star et al., 2002; Honkura et al., 2008). In this way the actin cytoskeleton of …
Dendritic spine - Wikipedia
WebSpinophilin is a dendritic spine protein (also known as neurabin) that acts as a scaffold and reorganizes actin (Allen, Ouimet, & Greengard, 1997 ). It does this via the activation of RhoA ( Ryan et al., 2009) ( Figure 1 ). Consistent with the repressive function of RhoA in spine formation, mice lacking spinophilin display increased spine ... WebThorns, spines, and prickles. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes ), are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals ... johan thomas lundbye malerier
