WEINSTEIN, R.B.*; LECESNE, C.; DURANDO, B.; LAYTON, C.; RUDINSKY, S.; TISCHLER, M.E.: Comparison of human insulin and its analogs on stimulation of in situ protein synthesis in rat soleus muscle Insulin analogs can be used to discriminate between metabolic and mitogenic (growth-related) pathways. This study compared the stimulatory effects of human insulin (HI) and two […]

COMPAAN, D.M.*; ELLINGTON, W.R.: Cloning, Expression and Characterization of a Contiguous, Dimeric Arginine Kinase Arginine kinase (AK) plays a central role in cellular energy homeostasis in a variety of invertebrates. The foot muscle of the razor clam Ensis directus contains extraordinarily high activities of AK [~1,000 enzyme units per g]. We have isolated this AK; […]

WEIHRAUCH, D.*; MARINI, A.M.; TOWLE, D.W.: Cloning and Expression of a Putative Rh-Like Ammonium Transporter from Gills of the Shore Crab Carcinus maenas The Rh blood group polypeptides of mammals are related to ammonium transporters in yeasts and plants. RhAG of red blood cells and a kidney homologue RhGK were recently shown to restore ammonium […]

SPAGNA, J.C.; GILLESPIE, R.G.: Cladistics and Biogeography of North American Grass-spiders Grass-spiders (Araneae, Agelenidae), with their ubiquitous sheet-and-funnel-webs, are among the most common and successful families of spiders in the northern hemisphere. Cladistic analysis of genitalic and somatic morphological characters from exemplar taxa of North American agelenid genera of subfamily Ageleninae revealed a single most […]

BAGATTO, B.P.*; BURGGREN, W.W.: Chronic Training Influences on Performance in Zebrafish Larvae, Danio rerio Zebrafish larvae (Danio rerio) of an albino color mutant (alb/alb) were divided into three different age groups (4, 9, and 21 days post-fertilization) and subjected to a continuous training water velocity of 5 body lengths per second. From behavioral observations at […]

KIM, H.-W.; YU, X.-L.; MYKLES, D.L.: Characterization of cDNAs encoding calpain genes expressed in lobster muscles Calpains constitute a diverse family of calcium-dependent cyteine proteinases in animal cells (83 calpain genes have been reported in 23 species). In decapod crustaceans, four calpain activities mediate molt-induced claw muscle atrophy. Selective degradation of myofibrillar proteins reduces muscle […]

LORENZ, D.L.*; HATLE, J.D.; LEWIS, H.D.; GOLEBIOWSKI, M.T.; BORST, D.W.: Characterization of a major hemolymph protein (MHPb) and its role in the ovarian development of the lubber grasshopper Hemolymph in the lubber grasshopper Romalea microptera contains high levels (up to 100 mg/ml) of proteins that may be used to store amino acids. SDS-PAGE disclosed three […]

MENDOZA, P.; MYKLES, D.L.: Characterization of a cDNA encoding lobster muscle troponin-T Three fiber types in decapod crustacean skeletal muscles differ in the expression of myofibrillar protein isoforms. Two slow types (slow-twitch or S1 and slow-tonic or S2) and one fast type are distinguished by differences in expression of three isoforms of troponin-T (TnT), the […]

SIMONSON, M.E.; MYKLES, D.L.: Characterization of a cDNA encoding lobster muscle troponin-I Skeletal muscle contraction is controlled by the regulatory proteins troponin and tropomyosin. Troponin is composed of three subunits: troponin-I, troponin-C, and troponin-T. At least five isoforms of troponin-I (TnI) have been identified in muscles from American lobster (Homarus americanus) using SDS-polyacrylamide gel electrophoresis. […]

THOMPSON, M.D.; KIM, H.-W.; MYKLES, D.L.: Characterization of a cDNA encoding lobster muscle troponin-C Troponin-C (TnC) is the calcium-binding subunit of the heterotrimeric troponin complex that mediates calcium-dependent contraction in skeletal muscle. Three isoforms are differentially expressed in fast and slow skeletal muscles of American lobster, Homarus americanus. In juveniles, fiber-type switching occurs as claws […]
