A blue-light-activated adenylyl cyclase mediates photoavoidance in Euglena gracilis
Blue light regulates processes such as the development of plants and fungi and the behaviour of microbes. Two types of blue-light receptor flavoprotein have been identified: cryptochromes, which haveExpand
Neuronal peptides induce oocyte maturation and gamete spawning of sea cucumber, Apostichopus japonicus.
Extracts prepared from tissues containing buccal ring nerve or longitudinal radial nerve of sea cucumber induce oocyte maturation and ovulation from ovarian tissues. We purified two small peptides, aExpand
The Drosophila fork head factor directly controls larval salivary gland-specific expression of the glue protein gene Sgs3.
The Drosophila Fork head protein participates in salivary gland formation, since salivary glands are missing in fork head embryos. Here we show that the fork head encoded protein binds to an upstreamExpand
Silk Gland Factor-1 Involved in the Regulation of Bombyx Sericin-1 Gene Contains Fork Head Motif (*)
Silk gland factor-1 (SGF-1) regulates transcription of the Bombyx sericin-1 gene via interaction with the SA site. In this study, two related SGF-1 polypeptides of apparent molecular masses of 40 andExpand
Expression pattern analysis of SGF‐3/POU‐M1 in relation to sericin‐1 gene expression in the silk gland
Embryonic and larval expression patterns of the sericin‐1 gene and its presumed transcription factor, SGF‐3/POU‐M1, in the silk gland were analyzed by in situ hybridization and immunohistochemistry.Expand
Embryonic silk gland development in Bombyx: molecular cloning and expression of the Bombyx trachealess gene
Abstract We describe embryonic development of the Bombyx silk gland. To extend the analysis further we isolated a Bombyx counterpart gene ofthe Drosophilatrachealess (trh) gene. Bombyx trh encodes aExpand
A relaxin-like peptide purified from radial nerves induces oocyte maturation and ovulation in the starfish, Asterina pectinifera
Gonad-stimulating substance (GSS) of starfish is the only known invertebrate peptide hormone responsible for final gamete maturation, rendering it functionally analogous to the vertebrate luteinizingExpand
Silk Gland Factor-2, Involved in Fibroin Gene Transcription, Consists of LIM Homeodomain, LIM-interacting, and Single-stranded DNA-binding Proteins*
Background: Silk gland factor-2 (SGF-2) is a key factor regulating tissue-specific expression of the fibroin gene. Results: SGF-2 is a 1.1-MDa heteromeric complex containing Awh, Ldb, Lcaf, andExpand
Preliminary study on the receptor of gonad-stimulating substance (GSS) as a gonadotropin of starfish.
Previously, the gonad-stimulating substance (GSS) which acts as the gonadotropin was purified from the starfish (Asterina pectinifera) and subsequently, its structure was deciphered. In this study,Expand
Molecular characterization of the major yolk protein of the Japanese common sea cucumber (Apostichopus japonicus) and its expression profile during ovarian development.
The most abundant protein in the coelomic fluid of the Japanese common sea cucumber (Apostichopus japonicus) was purified through two steps of liquid chromatography. Subsequent peptide sequencing andExpand
