Abstract:
Export of membrane proteins from the ER is believed to be selective and require transport signals, but the identity of such signals has remained elusive. The recycling type I membrane protein ERGIC-53 carries a C-terminal diphenylalanine motif that is required for efficient ER export. Here we show that this motif can be functionally substituted by a single phenylalanine or tyrosine at position -2, two leucines or isoleucines at position -1 and -2 or a single valine at position -1. These motifs are common among mammalian type I membrane proteins. A single C-terminal valine, but none of the othe

Abstract:
ABSTRACT Type III cytotoxins contribute to the ability of bacterial pathogens to subvert the host innate immune system. ExoS (453 amino acids) is a bifunctional type III cytotoxin produced by Pseudomonas aeruginosa. Residues 96 to 232 comprise a Rho GTPase activating protein domain, while residues 233 to 453 comprise a 14-3-3-dependent ADP-ribosyltransferase domain. An N-terminal domain (termed the membrane localization domain [MLD]) targets ExoS to the Golgi-endoplasmic reticulum (Golgi-ER) of mammalian cells. This study identifies an amino acid motif that is responsible for the membrane bind

Abstract:
When expressed in epithelial cells, dopamine transporter (DAT) was detected predominantly in the apical plasma membrane, whereas norepinephrine transporter (NET) was found in the basolateral membrane, despite 67% overall amino acid sequence identity. To identify possible localization signals responsible for this difference, DAT–NET chimeras were expressed in MDCK cells and localized by immunocytochemistry and transport assays. The results suggested that localization of these transporters in MDCK cells depends on their highly divergent NH2-terminal regions. Deletion of the first 58 amino acids

Sugar transporter proteins (STPs) are membrane proteins required for sugar transport throughout cellular membranes. They plays an imperative role in sugar transmission across the plant and determinants of crop yield. However, the analysis of these important STPs Sugars Will Eventually be Exported Transporters (SWEET) family in legumes is still not well-documented and remains unclear. Therefore, the in-silico analysis of STPs has been performed to unravel their cellular, molecular, and structural composition in legume species.

Indonesia has many cultural riches in the form of traditional fabrics, one of which is woven fabrics. Woven fabrics from each region showcase distinctive motifs, manifesting the local community’s daily life, culture, natural conditions, and beliefs. The diverse weaving motifs pose a challenge in determining the origin of the woven fabrics. It highlights the necessity of a system to detect and identify woven fabrics.

Abstract:
We recently discovered that MG53, a muscle-specific tripartite motif (TRIM) family protein, functions as a sensor of oxidation to nucleate the assembly of cell membrane repair machinery. Our data showed that disulfide bond formation mediated by Cys242 is critical for MG53-mediated translocation of intracellular vesicles toward the injury sites. Here we test the hypothesis that leucine zipper motifs in the coiled-coil domain of MG53 constitute an additional mechanism that facilitates oligomerization of MG53 during cell membrane repair. Two leucine zipper motifs in the coiled-coil domain of MG53

ABSTRACT The obligate human pathogen Haemophilus influenzae utilizes a siderophore-independent (free) Fe3+ transport system to obtain this essential element from the host iron-binding protein transferrin. The hFbpABC transporter is a binding protein-dependent ABC transporter that functions to shuttle (free) Fe3+ through the periplasm and across the inner membrane of H. influenzae. This investigation focuses on the structure and function of the hFbpB membrane permease component of the transporter, a protein that has eluded prior characterization.
