A pollen-specific novel calmodulin-binding protein with tetratricopeptide repeats.
Calcium is essential for pollen germination and pollen tube growth. A large body of information has established a link between elevation of cytosolic Ca(2+) at the pollen tube tip and its growth. Since the action of Ca(2+) is primarily mediated by Ca(2+)-binding proteins such as calmodulin (CaM), identification of CaM-binding proteins in pollen should provide insights into the mechanisms by whi...
متن کاملThe potato leafroll luteovirus 17K protein is a single-stranded nucleic acid-binding protein.
The potato leafroll luteovirus protein of Mr 17K (pr17), which is encoded by an open reading frame on the 3' half of the viral genome, was expressed by using bacterial expression vector systems. Fusion proteins were obtained for the full-length viral protein as well as its N-terminal acidic (GST/pr17N) and C-proximal (GST/pr17C) basic domains and used in nucleic acid-binding studies. Filter-bou...
متن کاملThe cellular retinoic acid binding protein I is dispensable.
The cellular retinoic acid binding proteins I and II (CRABPI and CRABPII) bind retinoic acid with high affinity, exhibit distinct patterns of expression during embryonic development, and are thought to play important roles in the RA signaling pathway. We have generated a targeted mutation of the CRABPI gene using the "hit-and-run" strategy and shown that it prevents the production of a function...
متن کاملNucleic acid recognition by tandem helical repeats.
Protein domains constructed from tandem α-helical repeats have until recently been primarily associated with protein scaffolds or RNA recognition. Recent crystal structures of human mitochondrial termination factor MTERF1 and Bacillus cereus alkylpurine DNA glycosylase AlkD bound to DNA revealed two new superhelical tandem repeat architectures capable of wrapping around the double helix in uniq...
متن کاملSearch for a prion-specific nucleic acid.
Diversity of prion strains was attributed to an elusive nucleic acid, yet a search spanning nearly two decades has failed to identify a prion-specific polynucleotide. In our search for a prion-specific nucleic acid, we analyzed nucleic acids in purified fractions from the brains of Syrian hamsters infected with Sc237 prions. Purification of Sc237 prions removed nucleic acids larger than 50 nucl...
