In nature, it exists as a native element, as an alloy combining with other metals (e.g., gold) and as minerals (e.g., chlorargyrite and argentite).
In plasma, VTNC exists in a native, monomeric conformation that lacks exposure of conformationally sensitive epitopes.
Weinreb and colleagues showed that the α-Syn protein exists in a native "unfolded" conformation, having an irregular structures [49].
In plasma, VTNC exists in a native, monomeric conformation, while during tissue injury or tumor growth, VTNC is recruited from the plasma into the extracellular matrix and assumes an active conformation through multimerization [14].
Experiments with NIH3T3 cells have shown that Raf-1, for instance, exists in a native heterocomplex with HSP90, cdc37 and other proteins (Grenert et al, 1997).
While the two studies suggest that normal cardiac epithelium represents a form of metaplastic epithelium secondary to gastro-esophageal reflux [ 21, 22], another study reported by Kilgore et al suggests that cardiac mucosa exists as a native structure [ 23].
Despite these variations, the superfunnel paradigm applies to all SEMs we have tested: For a majority of neutral nets across different models, there exists a funnel-like organization of native stabilities for the sequences in a neutral net encoding for the same structure, and the thermodynamically most stable sequence is also the most robust against mutation.
"The modern species of horse did evolve in North America, so it did exist as a native species at one time," said E. Gus Cothran, a professor of biomedical sciences at Texas A&M University's college of veterinary medicine, who has conducted horse research for the federal bureau.
Herein we found A. chroococcum crude PO to exist as a native active homotrimer (142 kDa), which is also active in monomeric and dimeric states.
Note: under this law, I do not exist as a Native Hawaiian- nor do my parents.
