Structural domains involved in the regulation of transmitter release by synapsins. (1/25)

Synapsins are a family of neuron-specific phosphoproteins that regulate neurotransmitter release by associating with synaptic vesicles. Synapsins consist of a series of conserved and variable structural domains of unknown function. We performed a systematic structure-function analysis of the various domains of synapsin by assessing the actions of synapsin fragments on neurotransmitter release, presynaptic ultrastructure, and the biochemical interactions of synapsin. Injecting a peptide derived from domain A into the squid giant presynaptic terminal inhibited neurotransmitter release in a phosphorylation-dependent manner. This peptide had no effect on vesicle pool size, synaptic depression, or transmitter release kinetics. In contrast, a peptide fragment from domain C reduced the number of synaptic vesicles in the periphery of the active zone and increased the rate and extent of synaptic depression. This peptide also slowed the kinetics of neurotransmitter release without affecting the number of docked vesicles. The domain C peptide, as well as another peptide from domain E that is known to have identical effects on vesicle pool size and release kinetics, both specifically interfered with the binding of synapsins to actin but not with the binding of synapsins to synaptic vesicles. This suggests that both peptides interfere with release by preventing interactions of synapsins with actin. Thus, interactions of domains C and E with the actin cytoskeleton may allow synapsins to perform two roles in regulating release, whereas domain A has an actin-independent function that regulates transmitter release in a phosphorylation-sensitive manner.  (+info)

Crystallization and preliminary X-ray diffraction analysis of calexcitin from Loligo pealei: a neuronal protein implicated in learning and memory. (2/25)

The neuronal protein calexcitin from the long-finned squid Loligo pealei has been expressed in Escherichia coli and purified to homogeneity. Calexcitin is a 22 kDa calcium-binding protein that becomes up-regulated in invertebrates following Pavlovian conditioning and is likely to be involved in signal transduction events associated with learning and memory. Recombinant squid calexcitin has been crystallized using the hanging-drop vapour-diffusion technique in the orthorhombic space group P2(1)2(1)2(1). The unit-cell parameters of a = 46.6, b = 69.2, c = 134.8 A suggest that the crystals contain two monomers per asymmetric unit and have a solvent content of 49%. This crystal form diffracts X-rays to at least 1.8 A resolution and yields data of high quality using synchrotron radiation.  (+info)

Backsteps induced by nucleotide analogs suggest the front head of kinesin is gated by strain. (3/25)

The two-headed kinesin motor harnesses the energy of ATP hydrolysis to take 8-nm steps, walking processively along a microtubule, alternately stepping with each of its catalytic heads in a hand-over-hand fashion. Two persistent challenges for models of kinesin motility are to explain how the two heads are coordinated ("gated") and when the translocation step occurs relative to other events in the mechanochemical reaction cycle. To investigate these questions, we used a precision optical trap to measure the single-molecule kinetics of kinesin in the presence of substrate analogs beryllium fluoride or adenylyl-imidodiphosphate. We found that normal stepping patterns were interspersed with long pauses induced by analog binding, and that these pauses were interrupted by short-lived backsteps. After a pause, processive stepping could only resume once the kinesin molecule took an obligatory, terminal backstep, exchanging the positions of its front and rear heads, presumably to allow release of the bound analog from the new front head. Preferential release from the front head implies that the kinetics of the two heads are differentially affected when both are bound to the microtubule, presumably by internal strain that is responsible for the gating. Furthermore, we found that ATP binding was required to reinitiate processive stepping after the terminal backstep. Together, our results support stepping models in which ATP binding triggers the mechanical step and the front head is gated by strain.  (+info)

Anatomical basis for camouflaged polarized light communication in squid. (4/25)

Camouflage is a means to defeat visual detection by predators, whereas visual communication involves a signal that is conspicuous to a receiver (usually a conspecific). However, most intraspecific visual signals are also conspicuous to predators, so that signalling can lead to the serious consequence of predation. Could an animal achieve visual camouflage and simultaneously send a hidden visual message to a conspecific? Here, we present evidence that the polarized aspect of iridescent colour in squid skin is maintained after it passes through the overlying pigmented chromatophores, which produce the highly evolved--and dynamically changeable--camouflaged patterns in cephalopods. Since cephalopods are polarization sensitive, and can regulate polarization via skin iridescence, it is conceivable that they could send polarized signals to conspecifics while staying camouflaged to fish or mammalian predators, most of which are not polarization sensitive.  (+info)

Preliminary time-of-flight neutron diffraction study on diisopropyl fluorophosphatase (DFPase) from Loligo vulgaris. (5/25)

The enzyme diisopropyl fluorophosphatase (DFPase) from Loligo vulgaris is capable of decontaminating a wide variety of toxic organophosphorus nerve agents. DFPase is structurally related to a number of enzymes, such as the medically important paraoxonase (PON). In order to investigate the reaction mechanism of this phosphotriesterase and to elucidate the protonation state of the active-site residues, large-sized crystals of DFPase have been prepared for neutron diffraction studies. Available H atoms have been exchanged through vapour diffusion against D2O-containing mother liquor in the capillary. A neutron data set has been collected to 2.2 A resolution on a relatively small (0.43 mm3) crystal at the spallation source in Los Alamos. The sample size and asymmetric unit requirements for the feasibility of neutron diffraction studies are summarized.  (+info)

Intense ultrasonic clicks from echolocating toothed whales do not elicit anti-predator responses or debilitate the squid Loligo pealeii. (6/25)

Toothed whales use intense ultrasonic clicks to echolocate prey and it has been hypothesized that they also acoustically debilitate their prey with these intense sound pulses to facilitate capture. Cephalopods are an important food source for toothed whales, and there has probably been an evolutionary selection pressure on cephalopods to develop a mechanism for detecting and evading sound-emitting toothed whale predators. Ultrasonic detection has evolved in some insects to avoid echolocating bats, and it can be hypothesized that cephalopods might have evolved similar ultrasound detection as an anti-predation measure. We test this hypothesis in the squid Loligo pealeii in a playback experiment using intense echolocation clicks from two squid-eating toothed whale species. Twelve squid were exposed to clicks at two repetition rates (16 and 125 clicks per second) with received sound pressure levels of 199-226 dB re1 microPa (pp) mimicking the sound exposure from an echolocating toothed whale as it approaches and captures prey. We demonstrate that intense ultrasonic clicks do not elicit any detectable anti-predator behaviour in L. pealeii and that clicks with received levels up to 226 dB re1 microPa (pp) do not acoustically debilitate this cephalopod species.  (+info)

Sodium flux ratio in Na/K pump-channels opened by palytoxin. (7/25)

Palytoxin binds to Na(+)/K(+) pumps in the plasma membrane of animal cells and opens an electrodiffusive cation pathway through the pumps. We investigated properties of the palytoxin-opened channels by recording macroscopic and microscopic currents in cell bodies of neurons from the giant fiber lobe, and by simultaneously measuring net current and (22)Na(+) efflux in voltage-clamped, internally dialyzed giant axons of the squid Loligo pealei. The conductance of single palytoxin-bound "pump-channels" in outside-out patches was approximately 7 pS in symmetrical 500 mM [Na(+)], comparable to findings in other cells. In these high-[Na(+)], K(+)-free solutions, with 5 mM cytoplasmic [ATP], the K(0.5) for palytoxin action was approximately 70 pM. The pump-channels were approximately 40-50 times less permeable to N-methyl-d-glucamine (NMG(+)) than to Na(+). The reversal potential of palytoxin-elicited current under biionic conditions, with the same concentration of a different permeant cation on each side of the membrane, was independent of the concentration of those ions over the range 55-550 mM. In giant axons, the Ussing flux ratio exponent (n') for Na(+) movements through palytoxin-bound pump-channels, over a 100-400 mM range of external [Na(+)] and 0 to -40 mV range of membrane potentials, averaged 1.05 +/- 0.02 (n = 28). These findings are consistent with occupancy of palytoxin-bound Na(+)/K(+) pump-channels either by a single Na(+) ion or by two Na(+) ions as might be anticipated from other work; idiosyncratic constraints are needed if the two Na(+) ions occupy a single-file pore, but not if they occupy side-by-side binding sites, as observed in related structures, and if only one of the sites is readily accessible from both sides of the membrane.  (+info)

Spectral and spatial properties of polarized light reflections from the arms of squid (Loligo pealeii) and cuttlefish (Sepia officinalis L.). (8/25)

On every arm of cuttlefish and squid there is a stripe of high-reflectance iridophores that reflects highly polarized light. Since cephalopods possess polarization vision, it has been hypothesized that these polarized stripes could serve an intraspecific communication function. We determined how polarization changes when these boneless arms move. By measuring the spectral and polarizing properties of the reflected light from samples at various angles of tilt and rotation, we found that the actual posture of the arm has little or no effect on partial polarization or the e-vector angle of the reflected light. However, when the illumination angle changed, the partial polarization of the reflected light also changed. The spectral reflections of the signals were also affected by the angle of illumination but not by the orientation of the sample. Electron microscope samples showed that these stripes are composed of several groups of multilayer platelets within the iridophores. The surface normal to each group is oriented at a different angle, which produces essentially constant reflection of polarized light over a range of viewing angles. These results demonstrate that cuttlefish and squid could send out reliable polarization signals to a receiver regardless of arm orientation.  (+info)

"Loligo" is not a medical term, but a genus name in the cephalopod family. It refers to several species of squid, including the common market squid ("Loligo opalescens") and the European squid ("Loligo vulgaris"). These squids are often used in scientific research and as a food source.

Decapodiformes is a taxonomic order of marine cephalopods, which includes squids, octopuses, and cuttlefish. The name "Decapodiformes" comes from the Greek words "deca," meaning ten, and "podos," meaning foot, referring to the fact that these animals have ten limbs.

However, it is worth noting that within Decapodiformes, octopuses are an exception as they only have eight arms. The other members of this order, such as squids and cuttlefish, have ten appendages, which are used for locomotion, feeding, and sensory perception.

Decapodiformes species are known for their complex behaviors, sophisticated communication systems, and remarkable adaptations that enable them to thrive in a variety of marine habitats. They play important ecological roles as both predators and prey in the ocean food chain.

Phosphoric triester hydrolases are a class of enzymes that catalyze the hydrolysis of phosphoric triesters into corresponding alcohols and phosphates. These enzymes play a crucial role in the detoxification of organophosphate pesticides and nerve agents, as well as in the metabolism of various endogenous compounds.

The term "phosphoric triester hydrolases" is often used interchangeably with "phosphotriesterases" or "organophosphorus hydrolases." These enzymes are characterized by their ability to cleave the P-O-C bond in phosphoric triesters, releasing a free alcohol and a diethyl phosphate moiety.

Phosphoric triester hydrolases have attracted significant interest due to their potential applications in bioremediation, biosensors, and therapeutics. However, it is important to note that the specificity and efficiency of these enzymes can vary widely depending on the structure and properties of the target compounds.

Mollusca is not a medical term per se, but a major group of invertebrate animals that includes snails, clams, octopuses, and squids. However, medically, some mollusks can be relevant as they can act as vectors for various diseases, such as schistosomiasis (transmitted by freshwater snails) and fascioliasis (transmitted by aquatic snails). Therefore, a medical definition might describe Mollusca as a phylum of mostly marine invertebrates that can sometimes play a role in the transmission of certain infectious diseases.

Octopodiformes is a taxonomic order that includes two main groups: octopuses (Octopoda) and vampire squids (Vampyroteuthis infernalis). This grouping is based on similarities in their fossil record and molecular data. Although they are commonly referred to as squids, vampire squids are not true squids, which belong to a different order called Teuthida.

Octopodiformes are characterized by several features, including:

1. A highly developed brain and complex nervous system.
2. Eight arms with suckers, but no tentacles.
3. The ability to change their skin color and texture for camouflage.
4. Three hearts that pump blood through their bodies.
5. Blue blood due to the copper-based protein hemocyanin.
6. A siphon used for jet propulsion and other functions, such as waste expulsion and mating.
7. Ink sacs for defense against predators.

Octopuses are known for their intelligence, problem-solving abilities, and short lifespans (usually less than two years). Vampire squids, on the other hand, live in deep ocean environments and have a unique feeding strategy that involves filtering organic matter from the water. They can also produce bioluminescent displays to confuse predators.

It is important to note that while Octopodiformes is a well-supported taxonomic group, there is still ongoing research and debate about the relationships among cephalopods (the class that includes octopuses, squids, cuttlefish, and nautiluses) and their classification.

Chromatophores are pigment-containing cells found in various organisms, including animals and plants. In animals, chromatophores are primarily found in the skin, eyes, and hair or feathers, and they play a crucial role in color changes exhibited by many species. These cells contain pigments that can be concentrated or dispersed to change the color of the cell, allowing the animal to camouflage itself, communicate with other individuals, or regulate its body temperature.

There are several types of chromatophores, including:

1. Melanophores: These cells contain the pigment melanin and are responsible for producing dark colors such as black, brown, and gray. They are found in many animals, including mammals, birds, reptiles, amphibians, and fish.
2. Xanthophores: These cells contain yellow or orange pigments called pteridines and carotenoids. They are found in many animals, including fish, amphibians, and reptiles.
3. Iridophores: These cells do not contain pigments but instead reflect light to produce iridescent colors. They are found in many animals, including fish, reptiles, and amphibians.
4. Erythrophores: These cells contain red or pink pigments called porphyrins and are found in some species of fish and crustaceans.
5. Leucophores: These cells reflect white light and are found in some species of fish, cephalopods (such as squid and octopuses), and crustaceans.

The distribution and concentration of pigments within chromatophores can be controlled by hormones, neurotransmitters, or other signaling molecules, allowing the animal to change its color rapidly in response to environmental stimuli or social cues.

An axon is a long, slender extension of a neuron (a type of nerve cell) that conducts electrical impulses (nerve impulses) away from the cell body to target cells, such as other neurons or muscle cells. Axons can vary in length from a few micrometers to over a meter long and are typically surrounded by a myelin sheath, which helps to insulate and protect the axon and allows for faster transmission of nerve impulses.

Axons play a critical role in the functioning of the nervous system, as they provide the means by which neurons communicate with one another and with other cells in the body. Damage to axons can result in serious neurological problems, such as those seen in spinal cord injuries or neurodegenerative diseases like multiple sclerosis.

The Stellate Ganglion is a part of the sympathetic nervous system. It's a collection of nerve cells (a ganglion) located in the neck, more specifically at the level of the sixth and seventh cervical vertebrae. The stellate ganglion is formed by the fusion of the inferior cervical ganglion and the first thoracic ganglion.

This ganglion plays a crucial role in the body's "fight or flight" response, providing sympathetic innervation to the head, neck, upper extremities, and heart. It's responsible for various functions including regulation of blood flow, sweat gland activity, and contributing to the sensory innervation of the head and neck.

Stellate ganglion block is a medical procedure used to diagnose or treat certain conditions like pain disorders, by injecting local anesthetic near the stellate ganglion to numb the area and interrupt nerve signals.

I'm sorry for any confusion, but "Polychaeta" is not a medical term. It is a taxonomic category in zoology, specifically referring to a class of annelid worms commonly known as bristle worms or polychaetes. These are segmented worms that have pairs of fleshy protrusions called parapodia on most or all segments, which they use for locomotion. Some species live in marine environments, while others can be found in fresh water or even terrestrial habitats. If you have a medical term you would like me to define, I'd be happy to help!

Cyanides are a group of chemical compounds that contain the cyano group, -CN, which consists of a carbon atom triple-bonded to a nitrogen atom. They are highly toxic and can cause rapid death due to the inhibition of cellular respiration. Cyanide ions (CN-) bind to the ferric iron in cytochrome c oxidase, a crucial enzyme in the electron transport chain, preventing the flow of electrons and the production of ATP, leading to cellular asphyxiation.

Common sources of cyanides include industrial chemicals such as hydrogen cyanide (HCN) and potassium cyanide (KCN), as well as natural sources like certain fruits, nuts, and plants. Exposure to high levels of cyanides can occur through inhalation, ingestion, or skin absorption, leading to symptoms such as headache, dizziness, nausea, vomiting, rapid heartbeat, seizures, coma, and ultimately death. Treatment for cyanide poisoning typically involves the use of antidotes that bind to cyanide ions and convert them into less toxic forms, such as thiosulfate and rhodanese.
