Activities of ATP binding cassette (ABC) proteins are regulated by multiple mechanisms, including protein interactions, phosphorylation, proteolytic processing, and/or oligomerization of the ABC protein itself. Here we present the structure of yeast cadm
The ANP/pGC-A signaling pathway lowers blood volume and blood pressure by increasing sodium/water excretion, vasorelaxation of vascular smooth muscle cells, increasing endothelial permeability and suppressing aldosterone13,15,16. Indeed, these actions of ANP have resulted recently in the engineering of ...

Describe the structure and function of a muscle fiber; summarize the process of muscle contraction. How contraction occurs in smooth muscle? How does muscle contraction happen? What is the role of actin and myosin in the process? Explain why the force of a muscle fiber's contraction is ...
What is the function of the smooth muscle in the walls of the alimentary canal? What are the accessory organs of digestion and their functions? Why is it important that chyme from the stomach is delivered to the small intestine slowly and in small amounts?
Understand the definition of the smooth endoplasmic reticulum. Identify the smooth ER’s function and review the structure of the organelle with an...
The reconstruction resolves past uncertainties and integrates previous data on cardiac muscle structure and function. It provides a new paradigm for interpreting structural, physiological and clinical observations, and for the design of potential therapeutic drugs....
Figure 1: Structure of the cytoplasmic domain of EzrA. (a) Ribbon diagram of the BsEzrA22–562 monomer coloured by triple helical bundle repeats from N- to C-terminus, red, yellow, green, blue and magenta. The C-terminal, four-helix bundle is coloured silver. This and all other structu...
When looking at the anterior aspect of knee joint anatomy, you will find the patella (kneecap). The patella is a small, triangular bone which sits in the quadriceps muscle at the front of the knee. The kneecap is lined with cartilage which is actually the thickest cartilage in the whole...
