Two distinct pathways have recently been proposed for the import of peroxisomal membrane proteins (PMPs): a Pex19p- and Pex3p-dependent class I pathway Pex3p-independent II pathway. We show here that Pex19p plays an essential role as chaperone full-length Pex3p in cytosol. forms soluble complex with newly synthesized cytosol directly translocates it to peroxisomes. Knockdown inhibits targeting results failure localization Pex3p. Moreover, we demonstrate Pex16p functions Pex3p-docking site...

We have identified a mouse PDZ protein that interacts with the activin type IIA receptor (ActRIIA), which we named receptor-interacting 1 (ARIP1). By using yeast two-hybrid screening, isolated cDNA clone of ARIP1 from brain library. detected two forms ARIP1, ARIP1-long and ARIP1-short, may be produced by alternative splicing. had one guanylate kinase domain in NH2-terminal region, followed WW domains five (PDZ1–5). ARIP1-short deletion region lacked domain. Both interacted ActRIIA through...

Using yeast two-hybrid screening, we have identified a mouse Postsynaptic density 95/Discs large/Zona occludens-1 (PDZ) protein that interacts with activin type II receptors (ActRIIs). We named the receptor-interacting 2 (ARIP2). ARIP2 was found to one PDZ domain in NH(2)-terminal region and interact specifically ActRIIs among for transforming growth factor beta family by domain. Interestingly, overexpression of enhances endocytosis reduces activin-induced transcription Chinese hamster ovary...

NELL1 is an extracellular protein inducing osteogenic differentiation and bone formation of osteoblastic cells. To elucidate the intracellular signaling cascade evoked by NELL1, we have shown that transiently activates MAPK cascade, induces phosphorylation Runx2, promotes rapid accumulation Tyr-phosphorylated proteins. Unlike BMP2, does not activate Smad cascade. These findings suggest upon binding to a specific receptor transduces signal through activation certain Tyr-kinases associated...

Abstract The distribution and the orgins of substance P (SP)‐positive fibers in papillae rat tongue were investigated by means indirect immunofluorescent method. Three types papilla contain SP‐positive fibers, though number ofthese varies from to papilla. circumvallate contains greatest followed foliate fungiform papillae; filiform lack fibers. papillar form dense bands lamina propria just beneath epithelium. Some enter epithelium taste buds. It should be stressed that not every bud is...

Messenger RNA (mRNA) has great potential to provide innovative medical solutions in the treatment of heart failure. Although lipid nanoparticles (LNPs) are an established mRNA delivery system, effectively delivering LNPs remains a significant challenge. Here, we evaluated efficacy transcatheter intracoronary (IC) administration compared intravenous (IV) and intramyocardial (IM) normal ischemia-reperfusion (I/R) model rabbit hearts using encapsulating Firefly Luciferase (FLuc) mRNA. In model,...

A peroxisomal C-tail-anchored type-II membrane protein, Pex26p, recruits AAA ATPase Pex1p-Pex6p complexes to peroxisomes. We herein attempted gain mechanistic insight into Pex26p function. Pex26pΔ33-40 truncated in amino-acid residues at 33-40 abolishes the recruiting of complex peroxisomes and fails complement impaired phenotype pex26 CHO cell mutant ZP167, thereby suggesting that localization Pex1p Pex6p is indispensable for transport matrix proteins.

Abstract Male hybrids produced from reciprocal crosses between Oryzias latipes and O. curvinotus are sterile, whereas females do lay eggs. Fertilized by the sperm of one parental species, such eggs develop into triploid males females. We examined allozyme patterns triploids that developed fertilized sperms non‐parental strains or a closely related luzonensis. Expression three allelic products in offsprings indicated unreduced diploidy hybrid In order to test clonality diploid females, we...

The peroxisome is a subcellular organelle that functions in essential metabolic pathways, including biosynthesis of plasmalogens, fatty acid β-oxidation very-long-chain acids, and degradation hydrogen peroxide. Peroxisome biogenesis disorders (PBDs) manifest as severe dysfunction multiple organs, the central nervous system (CNS), but pathogenic mechanisms PBDs are largely unknown. Because CNS integrity coordinately established maintained by neural cell interactions, we here investigated...
