Two components of the chloroplast envelope, Tic20 and Tic22, were previously identified as candidates for general protein import machinery by their ability to covalently cross-link nuclear-encoded preproteins trapped at an intermediate stage in across envelope (Kouranov, A., D.J. Schnell. 1997. J. Cell Biol. 139:1677–1685). We have determined primary structures Tic22 investigated localization association within envelope. is a 20-kD integral membrane component inner membrane. In contrast,...

Drought is one of the major abiotic stresses affecting plant growth, development and crop productivity. ABA responsive element binding factor (ABF) plays an important role in stress responses via regulating expression stress-responsive genes.In this study, a gene coding for ABF (PtrABF) was isolated from Poncirus trifoliata (L.) Raf. PtrABF had complete open reading frame 1347 bp, encoding 448 amino acid peptide, shared high sequence identities with ABFs other plants. subcellularly targeted...

Force-producing convergence (narrowing) and extension (lengthening) of tissues by active intercalation cells along the axis play a major role in axial morphogenesis during embryo development both vertebrates invertebrates, failure these processes human embryos leads to defects including spina bifida anencephaly. Here we use Xenopus laevis, system which polarized cell motility that drives this has been related forces close blastopore elongate body axis, examine myosin IIB extension. We find...

Ionic liquids (ILs) have been proven to be an effective technology for enhancing drug transdermal absorption. However, due the unique structural components of ILs, design efficient ILs and elucidation action mechanisms remain explored. In this review, basic principles ideal delivery system (TDDS) are discussed considering melting point, skin permeability, toxicity, which depend on molar ratios, types, functional groups ions inter-ionic interactions. Secondly, contributions development TDDS...

By tethering intermediate filaments (IFs) to sites of intercellular adhesion, desmosomes facilitate formation a supercellular scaffold that imparts mechanical strength tissue. However, the role IF–membrane attachments play in strengthening adhesion has not been directly examined. To address this question, we generated Tet-On A431 cells inducibly expressing desmoplakin (DP) mutant lacking rod and IF-binding domains (DPNTP). DPNTP localized plasma membrane led dissociation IFs from junctional...

The import of nucleus-encoded preproteins into plastids requires the coordinated activities membrane protein complexes that facilitate translocation polypeptides across envelope double membrane. Tic20 was identified previously as a component machinery inner by covalent cross-linking studies with trapped preprotein intermediates. To investigate role in import, we altered expression Arabidopsis ortholog (atTic20) antisense expression. Several lines exhibited pronounced chloroplast defects...

Little is known about how protocadherins function in cell adhesion and tissue development. Paraxial protocadherin (PAPC) controls sorting morphogenetic movements the Xenopus laevis embryo. We find that PAPC mediates these functions by down-regulating activity of C-cadherin. Expression exogenous C-cadherin reverses PAPC-induced gastrulation defects. Moreover, loss endogenous results elevated dorsal mesoderm interferes with normal blastopore closure, a defect can be rescued dominant-negative...

Abscisic acid (ABA) is an important phytohormone for plant growth, development and responding to stresses such as drought, salinity, pathogen infection. Pyrabactin Resistance 1 (PYR1)/PYR1-Like (PYL)/Regulatory Component of ABA Receptor (RCAR) (hereafter referred PYLs) has been identified the receptors. The PYL family members have well studied in many plants. However, not systematically at genome level cultivated tobacco (Nicotiana tabacum) its two ancestors. In this study, phylogenic...

Abstract Two integral outer envelope GTPases, Toc34 and Toc86, are proposed to regulate the recognition translocation of nuclear-encoded preproteins during early stages protein import into chloroplasts. Defining precise roles Toc86 has been complicated by inability distinguish their GTPase activities. Furthermore, assignment function is rendered equivocal recent reports suggesting that standard protocol for isolation chloroplasts results in significant proteolysis (B. Bolter, T. May, J. Soll...

Background Paraxial protocadherin (PAPC) and fibronectin leucine-rich domain transmembrane protein-3 (FLRT3) are induced by TGFβ signaling in Xenopus embryos both regulate morphogenesis inhibiting C-cadherin mediated cell adhesion. Principal Findings We have investigated the functional physical relationships between PAPC, FLRT3, C-cadherin. Although neither PAPC nor FLRT3 required for each other to adhesion, they do interact functionally physically, form a complex with cadherins. By itself...
