The PUF proteins in Trypanosoma brucei
… level. Proteins with an RNA-binding "Puf" domain are important for post-transcriptional control by modulation of mRNA stability and regulation of translation in other species. This suggested that Puf domain proteins might also have a similar role in trypanosomes. In addition to the …

Entropy Estimation for Arbiter PUF and Applications to Authenticated Key Exchange
Physically Unclonable Functions (PUF) are hardware-based security primitives whose unique challenge and response behavior serves as a "fingerprint" for device authentication, key generation, and anti-counterfeiting. Modeling and estimating the entropy of PUF responses to random challenges is the …

Molecular genetic analysis of puf andpuc operon expression in Rhodobacter sphaeroides 2.4.1
The deletion of the puf intercistronic terminator resulted in both the loss of the smallest 0.5-kilobase (kb) puf transcript in addition to an approximate 10-fold increase in transcriptional read-through of the mutated region to more distal pufL gene, suggesting that the proximal intercistronic …

Microscopic characterization of a putative ER-membrane targeted Puf RNA-binding protein in Arabidopsis thaliana
… cytoplasmic post-transcriptional control is the Puf family of RNA-binding proteins. Some of the general characteristics of plant Puf proteins, including their biochemistry, systematics and cell biology, have been studied in the Muench laboratory. The research reported in this thesis was aimed at …
