Shimizu, Masato, Hiroaki, Hidekazu, Kohda, Daisuke, Hosoya, Toshihiko, Akiyama-Oda, Yasuko, Hotta, Yoshiki, ...

Drosophila GCM (glial cell missing) is a novel DNA-binding protein that determines the fate of glial precursors from the neural default to glia. The GCM protein contains the functional domain that is...

Two proteins with myosin light chain kinase activity and electrophoretic molecular weights of 155,000 and 130,000 were each isolated from bovine stomach smooth muscle [Kuwayama, H., Suzuki, M., Koga,...

Genomic Organization of a Drosophila Phospholipase C, norpA, and Molecular Lesions in Two Temperature-Sensitive Mutants (1991)

Masai, Ichiro, Hotta, Yoshiki

The Drosophila mutant no receptor potential A (norpA) is the phototransduction-defective mutant which lacks phosphatidylinositol-specific phospholipase C (PI-PLC) activity. Recently, norpA cDNA was...

Heat Shock Gene Activation by Mutant Actin Is Independent of Myofibril Degeneration in Drosophila Muscle (1991)

Sakai, Yutaka, Okamoto, Hitoshi, Mogami, Kaname, Matsuo, Hiroki, Hotta, Yoshiki

Artificially mutagenized Drosophila Act88F actin genes with triple and double mutations were expressed in the indirect flight muscles of transgenic flies. The triple mutant actin, GD246T...

Actin with Tumor-Related Mutation Is Antimorphic in Drosophila Muscle: Two Distinct Modes of Myofibrillar Disruption by Antimorphic Actins (1990)

Sakai, Yutaka, Okamoto, Hitoshi, Mogami, Kaname, Yamada, Takuma, Hotta, Yoshiki

A mutant β-actin with an amino acid substitution from Gly-245 to Asp has been shown to be related to tumorigenic transformation of a human fibroblast cell line (Leavitt, J. et al (1987)Mol. Cell...

Analysis of Photoreceptor Membrane Turnover in a Drosophila Visual Mutant, rdgA, by Electron Microscope Autoradiography (1990)

Suzuki, Emiko, Hirosawa, Kazushige, Hotta, Yoshiki

A Drosophila visual mutant, rdgA, has photoreceptor cells whose rhabdomeres degenerate in several days after eclosion. Incorporations of 3H-amino acids, and 3H-mannose and 3H-glucosamine residues...

Membrane-Associated Phospholipase C of Drosophila Retina (1988)

Inoue, Hiroko, Yoshioka, Tohru, Hotta, Yoshiki

Phospholipase C activities against phosphatidylinositol 4,5-bisphosphate and phos-phatidylinositol have been examined using head homogenate of Drosophila visual mutants. In many mutants the enzyme...

Evidence that Arachidonic Acid Is Deficient in Phosphatidylinositol of Drosophila Heads (1985)

YOSHIOKA, Tohru, INOUE, Hiroko, KASAMA, Takeshi, SEYAMA, Yousuke, NAKASHIMA, Shigeru, NOZAWA, Yoshinori, ...

We have found that arachidonic (20 : 4) acid is indetectable in phosphatidylinositol and diacylglycerol extracted from Drosophila heads. After careful examinations of the lipid extraction processes...

Absence of Phosphatidylinositol Phosphodiesterase in the Head of a Drosophila Visual Mutant, norpA (no receptor potential A) (1985)

YOSHIOKA, Tohru, INOUE, Hiroko, HOTTA, Yoshiki

Phosphatidylinositol phosphodiesterase activity was found to be entirely absent in the head of the Drosophila visual mutant, norpA. It was also demonstrated that the enzyme activity was highly...

Identification of Drosophila Indirect Flight Muscle Myofibrillar Proteins by Means of Two-Dimensional Electrophoresis (1982)

MOGAMI, Kaname, FUJITA, Shinobu C., HOTTA, Yoshiki

When proteins of whole Drosophila thorax were analyzed by two-dimensional gel electrophoresis, 186 spots were detected by protein staining with Coomassie brilliant blue R-250. Two methods were...

Courtship in Drosophila Mosaics: Sex-Specific Foci for Sequential Action Patterns (1976)

Hotta, Yoshiki, Benzer, Seymour

Mosaic fate mapping is used to locate the foci determining sex-specific steps in the mating behavior of Drosophila. Male performance of following females and displaying wing vibration toward them...

Genetic Dissection of the Drosophila Nervous System by means of Mosaics (1970)

Hotta, Yoshiki, Benzer, Seymour

Given a mutant having abnormal behavior, the anatomical domain responsible for the deficit may be identified by the use of genetic mosaicism. Individuals may be produced in which a portion of the...

The gcm-motif: A novel DNA-binding motif conserved in Drosophila and mammals

Akiyama, Yasuko, Hosoya, Toshihiko, Poole, Anthony M., Hotta, Yoshiki

In the Drosophila nervous system, the glial cells missing gene (gcm) is transiently expressed in glial precursors to switch their fate from the neuronal default to glia. It encodes a novel 504-amino...

Actin gene mutations in Drosophila; heat shock activation in the indirect flight muscles

Hiromi, Yasushi, Hotta, Yoshiki

We have identified four mutations affecting the actin III isoform in the indirect flight muscles (IFM) of Drosophila. One mutation does not produce any protein product, and three direct the synthesis...
