Kinesin-3 motor UNC-104/KIF1A is essential for transporting synaptic precursors to synapses. Although the mechanism of cargo binding is well understood, little is known how motor activity is regulated. We mapped functional interaction domains between SYD-2 and UNC-104 by using yeast 2-hybrid and pull-down assays and by using FRET/fluorescence lifetime imaging microscopy to image the binding of ...
Assembly and maturation of synapses at the Drosophila neuromuscular junction (NMJ) depend on trans-synaptic neurexin/neuroligin signalling, which is promoted by the scaffolding protein Syd-1 binding to neurexin. Here we report that the scaffold protein spinophilin binds to the C-terminal portion of neurexin and is needed to limit neurexin/neuroligin signalling by acting antagonistic to Syd-1. L...
During synaptic development, presynaptic differentiation occurs as an intrinsic property of axons to form specialized areas of plasma membrane [active zones (AZs)] that regulate exocytosis and endocytosis of synaptic vesicles. Genetic and biochemical studies in vertebrate and invertebrate model systems have identified a number of proteins involved in AZ assembly. However, elucidating the molecu...
Patterning of the floral organs is exquisitely controlled and executed by four classes of homeotic regulators. Among these, the class B and class C floral homeotic regulators are of central importance as they specify the male and female reproductive organs. Inappropriate induction of the class B gene APETALA3 (AP3) and the class C gene AGAMOUS (AG) causes reduced reproductive fitness and is pre...
Active zones are presynaptic regions where synaptic vesicles fuse with plasma membrane to release neurotransmitters. Active zones are highly organized structurally and are functionally conserved among different species. Synapse defective-2 (SYD-2) family proteins regulate active zone morphology in Caenorhabditis elegans and Drosophila. Here, we demonstrate by immunoelectron microscopy that at C...
هدف از پژوهش حاضر بررسی تأثیر فعالیت ورزشی استقامتی بر بیان ژن SYD در نورون‌های حرکتی رت‌های مبتلا به نوروپاتی دیابت بود. بدین منظور، دوازده سر رت صحرایی بالغ نر نژاد ویستار به‌طور تصادفی در سه گروه چهارتایی دیابتی تمرین‌کرده (DT)، دیابتی تمرین‌نکرده (DC) و کنترل سالم (HC) قرار گرفتند. دو هفته پس از تزریق STZ برای القای دیابت، با اثبات نروپاتی دیابت توسط آزمون‌های رفتاری، پروتکل تمرین استقام...
As fundamental units of neuronal communication, chemical synapses are composed of presynaptic and postsynaptic specializations that form at specific locations with defined shape and size. Synaptic assembly must be tightly regulated to prevent overgrowth of the synapse size and number, but the molecular mechanisms that inhibit synapse assembly are poorly understood. We identified regulator of sy...
Organisms are continuously exposed to a myriad of environmental stresses. Central to an organism's survival is the ability to mount a robust transcriptional response to the imposed stress. An emerging mechanism of transcriptional control involves dynamic changes in chromatin structure. Alterations in chromatin structure are brought about by a number of different mechanisms, including chromatin ...
System on Devices (SyD) is a specification for a middleware to enable heterogeneous collections of information, databases, or devices (such as hand-held devices) to collaborate with each other. This paper illustrates the advantages of SyD by describing a prototype calendar of meetings application. This application highlights some of the technical merits of SyD by exploiting the use of coordinat...
Leukocyte-common antigen related (LAR)-like phosphatase receptors are conserved cell adhesion molecules that function in multiple developmental processes. The Caenorhabditis elegans ptp-3 gene encodes two LAR family isoforms that differ in the extracellular domain. We show here that the long isoform, PTP-3A, localizes specifically at synapses and that the short isoform, PTP-3B, is extrasynaptic...
