Activation of the novel PKC Apl II in sensory neurons by serotonin (5HT) underlies the ability of 5HT to reverse synaptic depression, but the pathway from 5HT to PKC Apl II activation remains unclear. Here we find no evidence for the Aplysia-specific B receptors, or for adenylate cyclase activation, to translocate fluorescently-tagged PKC Apl II. Using an anti-PKC Apl II antibody, we monitor tr...

The signal peptide of the outer membrane lipoprotein (OMLP) of Escherichia coli was shown to be capable of promoting protein translocation across mammalian microsomal membranes in vitro. We assayed translocation of a fusion protein containing the OMLP signal peptide and nine amino acids of OMLP fused in frame to beta-lactamase. The efficiency with which the mammalian translocation machinery rec...

Background: The human AML1 gene, located on chromosome 21, can be fused to the AML1- eight-twenty-one (ETO) oncoprotein on chromosome eight, resulting in a t(8;21)(q22;q22) translocation. Acute myeloid leukemia (AML) associated with this translocation is considered a distinct AML with a favorable prognosis. Due to the various incidences of the translocation, which is associated with geographic ...

The herpes simplex virus type 1 (HSV-1) tegument protein, VP22 has been reported to have the property of intercellular transport. The previous studies have shown that following expression of a fusion protein containing VP22 it spreads to every cell in a monolayer and concentrates in the nucleus. In spite of these reports, some studies have shown that VP22 trafficking and its nucleus accumulatio...

In order to reducing the risk of heavy metals concentration in plant tissues which are among the edible plants by human, find the active carbon ability in heavy metals removal from Lead (Pb) and Cadmium (Cd) contaminated soils and its effect on growth and nutrient absorption of Sweet basil, this greenhouse experiment was conducted in the faculty of agriculture, Islamic Azad University, Karaj br...

Background: Acute lymphoblastic leukemia (ALL) is the most common form of childhood cancer leading to cancer-related death in children. Most infants with ALL harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. Mixed-lineage leukemia-rearrangement (MLL-rearrange...

Amino-terminal signal sequences target nascent secretory and membrane proteins to the endoplasmic reticulum for translocation. Subsequent interactions between the signal sequence and components of the translocation machinery at the endoplasmic reticulum are thought to be important for the productive engagement of the translocon by the ribosome-nascent chain complex. However, it is not clear whe...
