Identification of the cohesion molecule, contact sites B, of Dictyostelium discoideum.
TLDR
Polyspecific antibodies were raised against vegetative cells of Dictyostelium discoideum, strain Ax2, and it was shown that CMC 1 Fab' bound to both the cytoplasm and the surface of fixed cells and also bound to thesurface of live cells. Expand
Dual role for Dictyostelium contact site B in phagocytosis and developmental size regulation
TLDR
Using a specific antibody against gpl26, it is shown that contact site B is a phagocytosis receptor and contact site A is involved in regulating the size of aggregates formed during morphogenesis; it also seems to be involved in cell–substratum adhesion but is not a developmental trigger. Expand
Hormones, receptors, and cellular interactions in plants
TLDR
The biochemistry and physiology of cyclic AMP in higher plants Russell P. Newton and Eric G. Brown explore the role of receptors in host-pathogen interactions and possible functions of plant lectins. Expand
Coh A, a mutation affecting the post aggregative related (par) cohesive system of Dictyostelium discoideum
TLDR
Genetic evidence presented here indicates that the two mutations have been separated by parasexual recombination yielding a Coh A, Rde A+ segregant class of which strain JC-36 is a prototype. Expand
Glucosylation of phosphorylpolyisoprenol and sterol at the plasma membrane of soya-bean (Glycine max) protoplasts.
TLDR
Although the synthesis of dolichol phosphate glucose and sterol glucosides occurred throughout the sucrose gradient, the specific activities of both glucosyltransferases were greatest in a fraction coincident with the radioactively labelled plasma membrane. Expand
Changes in the Cell Surface Level of GP126 during Development of Dictyostelium discoideum
TLDR
The developmental regulation of the vegetative cohesion molecule, gp126, has been monitored in the cellular slime mould Dictyostelium discoideum and by radio‐iodination of vegetative cells followed by liquid‐scintillation counting of gp 126, developmental‐regulation could be determined quantitatively. Expand
Stage-specific cohesion of cell ghosts and plasma-membrane fragments from Dictyostelium discoideum.
TLDR
Ghosts prepared from cells of the wild-type and of a cohesion-defective mutant that were harvested during growth and at aggregation and postaggregative stages of fruiting-body construction exhibited the same cohesive properties as the cells from which they were derived. Expand
Aggregation-related and post-aggregation-related cohesive systems in Dictyostelium discoideum involve stage-specific, Ca2+-dependent, di- or polymeric associations of membrane-bound moieties.
TLDR
It is shown that the ghosts of newly aggregation-competent cells and of cells from the 'Mexican hat (18 h) stage' of fruit construction can bind, each to its immobilized counterpart, but not heterologously, and suggests that both cohesive acts involve at least dimeric associations of molecules or molecular complexes located within or on juxtaposed membranes.

Receptors in tumour biology
TLDR
The biochemistry of ligand-receptor action is of fundamental theoretical and practical importance and this volume brings together for biochemists, immunologists and research workers in cancer essential aspects of the subject. Expand
