The proposed paper summarises the work done in WP4 of the EU sponsored RTD project TRAPIST. The needs of small to medium sized ports / terminals with 'multi-purpose' capability had to be addressed and the combination of: the absence of extensive IT support and how to deal with it, information flows to/from and within the terminal, cargo flows to/from and within the terminal and in association w...

The endo-lysosomal pathway is essential for intracellular transport and the degradation of extracellular cargo. The relationship between three populations of endo-lysosomal vesicles--Rab7-positive, LAMP1-positive, and both Rab7- and LAMP1-postive--was probed with fluorescence microscopy and single particle tracking. Of specific interest was determining if these vesicles were intermediate or ter...

Abstract Introduction: This is important to consider the health, social support, and marital satisfaction of drivers since they own one of the essential and stressful jobs in society. The purpose of this research was to investigate quality of life, marital satisfaction, and social support of the drivers referring to the cargo terminal of Yazd City. Methods: In order to collect data, 134 ...

The regulation of molecular motors is an important cellular problem, as motility in the absence of cargo results in futile adenosine triphosphate hydrolysis. When not transporting cargo, the microtubule (MT)-based motor Kinesin-1 is kept inactive as a result of a folded conformation that allows autoinhibition of the N-terminal motor by the C-terminal tail. The simplest model of Kinesin-1 activa...

The cargo that the molecular motor kinesin moves along microtubules has been elusive. We searched for binding partners of the COOH terminus of kinesin light chain, which contains tetratricopeptide repeat (TPR) motifs. Three proteins were found, the c-jun NH(2)-terminal kinase (JNK)-interacting proteins (JIPs) JIP-1, JIP-2, and JIP-3, which are scaffolding proteins for the JNK signaling pathway....

Peroxisomes require the translocation of folded and functional target proteins of various sizes across the peroxisomal membrane. We have investigated the structure and function of the principal import receptor Pex5p, which recognizes targets bearing a C-terminal peroxisomal targeting signal type 1. Crystal structures of the receptor in the presence and absence of a peroxisomal target, sterol ca...

Tobacco Joka2 protein is a hybrid homolog of two mammalian selective autophagy cargo receptors, p62 and NBR1. These proteins can directly interact with the members of ATG8 family and the polyubiquitinated cargoes designed for degradation. Function of the selective autophagy cargo receptors relies on their ability to form protein aggregates. It has been shown that the N-terminal PB1 domain of p6...

Cytoplasmic dynein transports membranous cargoes along microtubules, but the mechanism of dynein-cargo interaction is unclear. From a genetic screen, we identified a homologue of human Hook proteins, HookA, as a factor required for dynein-mediated early endosome movement in the filamentous fungus Aspergillus nidulans. HookA contains a putative N-terminal microtubule-binding domain followed by c...

The protein Pex19p functions as a receptor and chaperone of peroxisomal membrane proteins (PMPs). The crystal structure of the folded C-terminal part of the receptor reveals a globular domain that displays a bundle of three long helices in an antiparallel arrangement. Complementary functional experiments, using a range of truncated Pex19p constructs, show that the structured alpha-helical domai...
