Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells
Advanced Functional Materials, EarlyView.Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Advanced Functional Materials, EarlyView.There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Advanced Functional Materials, EarlyView.Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

The role of Ca(2+) as a key and pivotal second messenger in cells depends largely on a wide number of heterogeneous so-called calcium binding proteins (CBP), which have the ability to bind this ion in specific domains. CBP contribute to the control of Ca(2+) concentration in the cytosol and participate in numerous cellular functions by acting as Ca(2+)

Sarcoplasmic calcium-binding protein
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995Sarcoplasmic calcium-binding proteins (SCPs) are members of the EF-hand calcium-binding protein family which are characterized by the presence of helix-loop-helix motifs in their amino acid sequence. SCPs have an M(r) of approximately 20,000, a pI of approximately 5 and interact with two to three calcium ions (Ca2+) with a KD of 10(-7) to 10(-8) M. Mg2+

Extracellular calcium-binding proteins
Current Opinion in Cell Biology, 1996Point mutations in Ca2+-binding sites of extracellular matrix proteins have been identified as the cause of human disorders such as Marfansyndrome and pseudoachondroplasia. Although the modes of Ca2+ binding and the effects of point mutations are not yet understood in these two cases, new insight was recently gained by X-ray and NMR structure ...

Annual Review of Biochemistry, 1976
Calcium binding, which appears to be either specific or physiologically significant, has been reported for 70 norminally "different" proteins. First, I catalog these proteins. Only a few recent or general references can be cited. Those proteins that serve critical physiological functions or that may be regarded as chemical prototypes are discussed in ...

Publisher Summary This chapter describes calcium-binding proteins. Calcium is of widespread and fundamental importance in biochemistry because the calcium ion functions as a second messenger—that is, one whose signals are propagated by proteins specifically evolved for this purpose.
