(3) An additional 14 leader peptides in this collection (all of those that contain an arginine at -10) conform to this motif.
(4) In addition, region III has some structural features similar to a conserved motif found in complement receptor 1, the human C3b receptor.
(5) A new alternative splice site was incidently found 81 nucleotide downstream of motif II in both normal and truncated 4.1 mRNA.
(6) The same RNA-protein motif is used, through iron-dependent degradation of transferrin receptor mRNA, to decrease synthesis of the receptor and cellular iron uptake.
(7) Comparison of the human and mouse repeats revealed a highly conserved Glu-Asp core in each unit, implicating the functional significance of this motif.
(8) The three-dimensional solution structure of a zinc finger nucleic acid binding motif has been determined by nuclear magnetic resonance (NMR) spectroscopy.
(9) Sequence comparison programs suggested the presence of domains related to the RNA recognition motif found in other RNA-binding proteins, and deletion analysis revealed that the carboxyl-terminal 195 amino acids of the recombinant PTB was sufficient for specific binding to pre-mRNAs.
(10) Since similar loop conformations form similar "words", the structural sequence facilitates the search for common structural motifs in a family of loops.
(11) A new repetitive DNA region was identified in the non-transcribed spacer of human rDNA, namely a long (4.6 kb) sequence motif (Xbal element) was present in two copies.
(12) X-ray analysis of these crystals will permit direct visualization of the specific structural motifs and chemical features that underlie phospholipase neurotoxicity.
(13) Information about the three-dimensional structure or function of a newly determined protein sequence can be obtained if the protein is found to contain a characterized motif or pattern of residues.
(14) For PPD-specific TCCs, a possible biased usage of V beta 8, as well as possible preferential usage of a CDR3 motif, were found.
(15) This phenomenon was observed by using wheat-germ RNA polymerase II and a series of double-stranded template polymers containing palindromic repeating motifs of 6-16 bp, with regulatory alternating purine and pyrimidine bases such as d[ATA(CG)nC].d[TAT(GC)nG], with n = 1, 3 or 6 referred to as d(GC), d(GC)3 or d(GC)6, respectively.
(16) A sequence between residues 302 and 320 homologous to a metal-binding "finger" motif is therefore not required for origin-specific binding.
(17) In this report, we examined the functional significance of these six motifs for the UL9 protein through the introduction of site-specific mutations resulting in single amino acid substitutions of the most highly conserved residues within each motif.
(18) These sequences have a number of similar motifs at, or immediately following, the end of the coding regions, motifs that may be involved in their S mRNA transcription termination processes.
(19) The TV campaign, created by ad agency Leo Burnett, uses imagery and motifs more closely associated with Christmas than summer.
(20) Interestingly, the helical motif prefers to assemble parallel to the wall, whereas the beta-barrel, predominantly assembles with its principal axis perpendicular to the wall.
