Abstract:

Actin is involved in cell movement, maintaining cell shape and anchoring cytoskeletal proteins. These functions are regulated by many actin-binding proteins, including those of the gelsolin superfamily. Gelsolin superfamily members regulate actin organization by severing, capping F-actin, nucleating the formation of F-actin and/or bundling F-actin. Although abundant structures are available for gelsolin and gelsolin fragments in complexes with actin, the detailed mechanisms for gelsolin activation, and for gelsolin severing and capping of F-actin are still unknown. Structures for gelsolin fami

<i>Salmonella</i> invasion protein C (SipC) and SipA bind actin directly. SipC inserts into the host cell plasma membrane from where it promotes effector delivery and is essential for <i>Salmonella</i> invasion. SipC-C (residues 200-409) directly nucleates actin polymerisation <i>in vitro</i> and induces cytoskeletal rearrangements at the leading edge when expressed in cells. By analysis a panel of SipC-C derivatives in transfected cells, a region spanning residues 377-409 was defined as necessary for actin reorganisation and leading-edge localisation.

The alpha-actinin residues involved in the interaction of chicken smooth muscle alpha-actinin with F-actin were defined by co-sedimentation. Residues 120 to 140 of alpha-actinin were identified as essential with residues 141 to 159 and 1 to 107 contributing to the interaction. Temperature dependent binding and the lack of inhibition by high salt concentrations implicated hydrophobic interactions in the binding mechanism. Further characterisation of the binding interaction using stopped-flow techniques determined a K for the interaction of 0.82 muM at 15°C and 2.38 muM at 25°C. These techniques

Hearing requires proper function of the auditory hair cell, which is critically dependent upon its actin-based cytoskeletal structure. Eleven point mutations in gamma (γ) nonmuscle actin have been identified as causing progressive autosomal dominant nonsyndromic hearing loss (DFNA20/26); however, exactly why these mutations lead to deafness is unclear. Organization, stability, and repair of the hair cell cytoskeleton are highly regulated by actin binding proteins (ABPs), and two of the mutations, K118M and K118N, are located near an area of the actin monomer believed to be important in actin-A

Abstract:

The cytoskeleton is a remarkable system of filaments that helps in the organisation and functioning of living cells. In plant cells, this cytoskeleton comprises actin microfilaments and microtubules that polymerise from actin and tubulin respectively. While these proteins are highly conserved in eukaryotes, the plant cytoskeleton performs many plant-specific functions. The organisation and functions of the cytoskeleton are determined by a plethora of accessory proteins (actin-binding proteins, microtubule-associated proteins) that link the cytoskeletal filaments to other cell components and to

Abstract:

Spatiotemporal increase of the intracellular Ca2+ is the most universal way to regulate the function of a eukaryotic cell. Owing to a host of actin-binding proteins and enzymes whose activities are modulated by the local concentration of Ca2+, free Ca2+ in cytosol serves as a pivotal second messenger in a variety of cell functions. The rise and fall of intracellular Ca2+ wave has been best illustrated in eggs at fertilization. However, the molecular mechanism by which intracellular Ca2+ is increased in the fertilized egg is largely unknown despite the discoveries of the distinct Ca2+-mobilizin

Abstract:

Abstract Filamins are large dimeric proteins that cross-link actin into three-dimensional bundles or orthogonal networks. In addition to an actin-binding domain, each filamin monomer contains 24 immunoglobulin-like domains separated by flexible regions between domains 15–16 and 23–24. Dimerisation of filamin occurs through the Ig-like domain 24. Filamins bind to a variety of molecules. They provide a link between the plasma membrane and the cytoskeleton through interactions with transmembrane receptors, and at the same time, serve as a platform for signalling molecules. Filamins are involved i

Abstract:

Rationale: Calcium (Ca2+) activation of the thin filament cannot solely explain force regulation in cardiac muscles, including the rates of force development, force responses to mechanical perturbations, and relaxation. Cooperative activation between myosin cross-bridges induced by the strong-binding between myosin•actin•ADP has been suggested to also contribute to thin filament activation and force development. Little is known about ADP-induced activation in striated muscles. Hypotheses: ADP-induced activation and cooperativity between myosin cross-bridges contributes to cardiac force regulat

Abstract:

Calponins (CaPs) are actin-binding proteins that stabilize actin filaments. Mammals express three genetic isoforms in a tissue-specific manner. CaPs share an N-terminal calponin-homology (CH) domain followed by short tandem sequence repeats termed calponin-like (CLIK ) repeats. The extreme C-termini of CaPs contain isoform-specific tail sequences. Basic calponin (hlCaP) was the first isoform to be discovered 22 years ago in an attempt to identify troponin-like proteins in smooth muscle. The scope of this thesis was to reveal the mechanisms that regulate the actin-binding activity of hlCaP.

Abstract:

The NET protein superfamily is a recently discovered family of novel, plant-specific actin binding proteins. The identification of this family represents a significant discovery as the plant cytoskeleton is not identical to the animal cytoskeleton and plant cells show plant specific processes and subcellular structures which rely on actin. There is a need for plant specific proteins which are capable of modelling actin within plant cells. The NET family comprises thirteen proteins in Arabidopsis thaliana, which share the NET actin binding domain (found at the N-terminal end of each protein). B

ABSTRACT Regulation of gene transcription by structural interconversions of genomic DNA is an emerging biochemical and genetic paradigm that adds to the already diverse repertoire of eukaryotic gene regulatory mechanisms.

Despite its acceptance, this concept has been minimally described at the
