Isolation and characterization of a new peroxiredoxin from poplar sieve tubes that uses either glutaredoxin or thioredoxin as a proton donor.
TLDR
It is proposed that the poplar protein represents a new type of Prx that differs from the so-called 2-Cys and 1-CYS Prx, a suggestion supported by the existence of natural fusion sequences constituted of a Prx motif coupled to a Grx motif. Expand
Nuclear basic proteins in spermiogenesis.
TLDR
The molecular characteristics of the protamines as well as number of protamine types present in the spermatozoon vary from species to species, and in some cases, protamine-encoding genes, although present, are not expressed to a significant level. Expand
Innate Immune Responses of a Scleractinian Coral to Vibriosis*
TLDR
The data show that damicornin is constitutively transcribed in ectodermal granular cells, where it is stored, and further released in response to nonpathogenic immune challenge, the first evidence of AMP gene repression in a host-Vibrio interaction. Expand
Purification and characterization of nuclear basic proteins of human sperm.
TLDR
Highly purified nuclei were obtained from human sperm without protein loss through the use of CHAPS (3-cholamidopropyl)dimethylammonio]-1-propanesulfonate, a newly available detergent, which reveals two protamines previously considered as two different proteins are in fact the same protein with different degrees of phosphorylation. Expand
Microglia of medicinal leech (Hirudo medicinalis) express a specific activation marker homologous to vertebrate ionized calcium‐binding adapter molecule 1 (Iba1/alias aif‐1)
TLDR
It is demonstrated that most of leech microglial cells migrating and accumulating at the lesion site specifically expressed the activation marker HmIba1, which constitutes the first report on an Iba1 protein in the nervous system of an invertebrate. Expand
The structure of ubiquitinated histone H2B.
TLDR
Edman degradations of both peptides established that ubiquitin is attached to the epsilon‐amino group of lysine 120 in both calf and pig uH2B by an iso‐peptide bond to the C‐terminal glycine 76 of Ubiquitin. Expand
cDNA cloning of the HMGI-C phosphoprotein, a nuclear protein associated with neoplastic and undifferentiated phenotypes.
TLDR
Analysis of mRNA levels demonstrate that the HMGI-C gene is not expressed in a variety of mouse tissues but is expressed in Lewis lung carcinoma cells. Expand
NMR structures and activity of a novel alpha-like toxin from the scorpion Leiurus quinquestriatus hebraeus.
TLDR
Three turn regions involved in the functional binding site of the anti-insect LqhalphaIT toxin reveal significant differences in the Lqh III structure, which affords additional important elements to the definition of the new alpha-like group of scorpion toxins and the mammal versus insect scorpion toxin selectivities. Expand
Molecular Characterization of Two Novel Antibacterial Peptides Inducible upon Bacterial Challenge in an Annelid, the Leech Theromyzon tessulatum*
TLDR
The presence of antimicrobial peptide genes in leeches and their expression in a specific tissue functionally resembling the insect fat body provide evidence for the first time of an antibacterial response in a lophotrochozoan comparable to that of holometabola insects. Expand
DNA-interacting Proteins in the Spermiogenesis of the MolluscMurex brandaris *
TLDR
The results reveal that spermiogenic nuclear proteins are protamine precursors that are subjected to a substantial number of small N-terminal deletions that gradually modify their overall charge, promoting an efficient and extremely tight packaging of DNA. Expand
