Cells Weekly #45

This time, Cells (every-other-week) Weekly is here a bit early, but as always is in the interests of promoting science posts relating (however broadly) to my interests of cell and molecular biology.

The Nuclear Pore Complex: What Else Is In It? – A new NCB paper brings to light very unexpected proteins contributing to nuclear pore complexes, dynein light chain. Who’d have thought? At The Daily Transcript.

Adiponectin – Interested in an encyclopedic blog post? Then check out this entry on a hormone, adiponectin, and its physiological and biochemical roles in fat cells and obesity. At Science and Reason.

Complexin…Not So Inconsequential Anymore – A new protein has been discovered in neurons which regulates neurotransmitter release after the action potential has passed. In doing so this protein, complexin, influencing synaptic growth and neural rewiring. By Lua Yar at Pharyngula.

The Hox Code – Hox genes may recapitulate axial patterning in development, not merely being specified by their cis-elements but also in their chromosomal arrangements. Combinations and arrangements thereof appear critical. At Pharyngula.

3D Reconstruction of the Presynaptic Terminal – The title says it all. Check it out for an interesting image. At the Neurophilosopher’s Blog.

Multicellular Logic Circuits, Part II: Cells – A relatively new science blog brings us an educational review of eukaryotic gene regulatory networks. Go check it out if you need a crash course in signal transduction. At Nerd Wisdom.

Michaelis-Menten Enzyme Kinetics – A primer on enzyme kinetics, AKA the chemical workhorses of the cell. At Biocurious.

Front-Loading with Homeodomains – Ditching parsimony, MikeGene continues to argue for divine origins. Check out his blog for the theist’s interpretation of biology. At the Design Matrix.

Carnivals: Encephalon #32, Gene Genie #16, Tangled Bank #89.
