Gil Mor,Roberto Romero,Vikki M. Abrahams translocated to interior compartments within the organelle. This observation is true both for .-barrel-type proteins and for proteins that contain hydrophobic .-helical transmembrane segments. In this review, we describe what is known about the various steps leading to protein insertion into the ou

Immunomodulatory Agents from Plantshe regulation of many cellular processes. These protein kinases were originally identified based on their rapid activation by insulin. In this review we concentrate on examining the evidence for and against a role for the MAP kinases Erk-1 and Erk-2 in mediating the effects of insulin While there is

The role of CpG in DNA vaccines,ceptor and several coreceptors initiate parallel and interdependent signal transduction pathways. Protein-tyrosine phosphorylation is important in the initiation of cellular responses by the T-cell antigen receptor. As the T-cell receptor has no intrinsic protein-tyrosine kinase activity, activation

s. The single polypeptide chains of all isoforms contain conserved (C.—C.) and variable (V.—V.) regions, and are composed of a catalytic domain and a regulatory domain The catalytic domain is active without cofactors after proteolytic removal of the regulatory domain by cleavage in the V. region.

The ribosomes are directed to the RER membrane by a cytoplasmic ribonucleoprotein particle, the signal recognition particle (SRP). SRP fulfills its task by virtue of three distinguishable

The MADS-box is a conserved motif found within the DNA-binding domains of these proteins and the name refers to four of the originally identified members: .CM1, .G, .EFA and .RF. Several proteins within this family

Joint venture manager as a common agency,ssues. The ‘area codes’ used to control the trafficking are adhesion molecules, receptors which pick up external signals, and mediators of cell-to-cell communication. Platelet-activating factor (PAF) is a mediator that belongs to this class of ‘area-code’ molecules. PAF is an acetylated derivative o
