Its recognition sequence is AAC N6 GTGC but cleavage occurs at a site distant from this sequence (reviewed in [8]. The restriction activity of EcoKI can be attenuated temporarily by the cell, a phenomenon referred to as restriction alleviation (RA).
Telomere length is regulated by the enzyme telomerase, which consists of a catalytic telomerase reverse transcriptase (TERT) and an RNA template (TR) that encodes the telomeric DNA sequence, reviewed in [9].
In this process, short 19 25 nt double-stranded RNA (dsRNA) duplexes mediate the degradation of mRNA transcripts that contain an exact match to the dsRNA sequence (reviewed in [3]).
The mammalian ligands for these integrins contain an RGD (Arg-Gly-Asp) sequence (reviewed in Barczyk et al., 2010).
The first 89 amino acids of the pGHRH-R are replaced in SV-1 receptor by a different 25-amino acid sequence (reviewed in Schally and Varga, 2006).
The C-terminal tail of MUC1 has a number of potential endosomal cycling/sorting motifs, based on the 'YXXPhi' sequence (reviewed in Bonifacino and Traub, 2003).
For example, sequencing of all protein coding genes in several solid tumours, including glioblastomas, colorectal, pancreatic and breast cancers, revealed approximately 40 80 mutations per tumour, which alter protein sequence (reviewed in Fox et al, 2009).
Genes required for metabolism of alternative sugars, such as sucrose, galactose, and maltose, respond to Snf1 through the Mig1 transcriptional repressor, a C2H2 zinc finger protein that binds to a GC-rich consensus sequence (reviewed in Schuller 2003).
Secondly, inhibition of NMD has been proposed as a clinical treatment for genetic abnormalities, such as a proportion of cystic fibrosis cases, that are caused by nonsense mutations producing premature termination codons within the coding sequence (reviewed by Bhuvanagiri et al. [ 39]).
Bacteria, like eukaryotes, contain subcellular structures that function to compartmentalize certain metabolic steps or reaction sequences (reviewed in [1]).
