Random Facts

• The dystrophin gene is one of the largest known genes. Dystrophin - a large protein which connects the thin actin filaments to the transmembrane protein beeta-dystroglycan in the sarcolemma.

Duchenne's muscular dystrophy (mutations of the dystrohin gene cause the dystrophin be absent from the muscles.

Becker's muscular dystrophy - milder form. Dystrophin is present, but altered or reduced in amount.

Overview

I've finished reviewing cell biology at last - organelles, cell's transport and communication systems. It was quite an interesting subject, I even felt somehow thrilled. I did it rather thoroughly, using different sources. Reading the experience of other's, using too many recources is discouraged, but I just can't do otherwise, I need different approaces to begin to understand the topic fully. I also guess, as I don't feel the pressure of exam, I can enjoy the process of learning more - it's just for myself.
Right now I've started neurophyiology.

Random Facts.

• Active transopr of Na- and K-ions (Na-K-ATPase) is one of the major energy using process in the body. Thus it accounts for a large part of the basal metabolism. On average, it accounts 24% of energy utilized by cells, and in neurons it accounts 70%.

• About 50% of all known drugs work through G-protein-linked receptors.

• Actin is the most abundant protein in the cells. (At times up to 15% of all proteins of a cell). A structural component of microfilaments (thin filaments).
