Serine Threonine protein kinase C PKC

The serine/threonine protein kinase C (PKC) family consists of at least 11 mammalian isozymes belonging to a larger subclass of protein kinases termed the adenine-guanine-cytosine (AGC) kinases. PK...

Antibody classes

An antibody, also known as an immunoglobulin, is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a...

Tumor Antigens

Tumor antigen is an antigenic substance produced in tumor cells, i.e., it triggers an immune response in the host. Tumor antigens are useful in identifying tumor cells and are potential candidates f...

Cell architecture: Finding common ground

(Carnegie Institution) When it comes to cellular architecture, function follows form. Plant cells contain a dynamic cytoskeleton, which is responsible for directing cell growth, development, movement,...

Structure and insights into the function of a Ca2+-activated Cl− channel

The X-ray crystal structure of a eukaryotic Ca2+-activated chloride channel, BEST1, and its function in liposomes are described; the structure shows that Ca2+ binds to the cytosolic region of this pen...

Structural biology: Hand in hand structure and function of T6SSs

Two studies report the atomic structure of two bacterial type VI secretion systems and identify specific domains that are essential for their function.

Dark neural patches in the neostriatum

Researchers at the Okinawa Institute of Science and Technology Graduate University's Brain Mechanisms for Behaviour Unit have found a surprise upon mapping the precise connectivity inside a brain stru...

How cells communicate

(Karlsruher Institut für Technologie (KIT) ) During embryonal development of vertebrates, signaling molecules inform each cell about its position. So the cell can develop its special structure and fu...

The geometry of RNA and its 3D structure

To understand the function of an RNA molecule, similar to the better-known DNA and vital for cell metabolism, we need to know its three-dimensional structure. Unfortunately, establishing the shape of ...

CetZ tubulin-like proteins control archaeal cell shape

Tubulin is a major component of the eukaryotic cytoskeleton, controlling cell shape, structure and dynamics, whereas its bacterial homologue FtsZ establishes the cytokinetic ring that constricts durin...

MU scientist and inventor contributes to the study of cell genetics

(University of Missouri-Columbia) Cytogenetics is a branch of science that studies the structure and function of cells with a focus on the chromosomes found within the cell. Often, plant cell research...

Removal of annexin V-positive sperm cells for intracytoplasmic sperm injection in ovum donation cycles does not improve reproductive outcome: a controlled and randomized trial in unselected males.

To determine the effect of removing presumptive apoptotic sperm cells from samples from unselected males by means of magnetic activated cell sorting (MACS) on live-birth delivery rates after intracyto...

The Billion Cell Construct: Will Three-Dimensional Printing Get Us There?

How structure relates to function-across spatial scales, from the single molecule to the whole organism-is a central theme in biology. Bioengineers, however, wrestle with the converse question: will f...

Functional Architecture of the Retina: Development and Disease.

Structure and function are highly correlated in the vertebrate retina, a sensory tissue that is organized into cell layers with microcircuits working in parallel and together to encode visual informat...

Up against the wall: Is yeast cell wall integrity ensured by mechanosensing in plasma membrane microdomains?

Yeast cell wall integrity (CWI) signaling serves as a model for the regulation of fungal cell wall synthesis and provides the basis for the development of antifungal drugs. A set of five membrane-span...

The role of disulfide bonds in structure and activity of chlorotoxin.

Background: Chlorotoxin is a small scorpion peptide that inhibits glioma cell migration. We investigated the importance of a major component of chlorotoxin's chemical structure - four disulfide bonds ...
