The PDCD4 homologs in Cycas micholitz and Sundacarpus amarus contain deletions in each MA3 domain relative to the early land plants and angiosperms, perhaps suggesting a unique feature of gymnosperm PDCD4 homologs.
In Arabidopsis, only one RBR gene has been found, and the presence of two distinct RBR genes have been suggested to a unique feature of grasses [ 59].
There are clinical, genetic and radiological features that are associated with PsA and that together suggest a unique clinical entity.
On the contrary, in the JF2 protein of Shistosoma mansoni, the position equivalent to Lys60 of moesin is occupied by a glutamic acid residue, and no conservation of residues 275, 278, and 279 in the JF2 protein was found, suggesting a unique structural feature for this S histosoma protein.
The severe neuronal loss observed in CA2/3 of this case bears similarity to that described in association with A53T SNCA mutation [ 48, 77] and in cases of multiplication of SNCA, though this pattern of loss was suggested to be a unique feature of the latter [ 21] (Table 2).
The lack of connection between discussion features and correctness of a group's answers has been found by us with advanced students (Knight et al., 2013) and by others with younger students (e.g., Sampson and Clark, 2008), suggesting it is not a unique feature of any particular level of student.
Interestingly, gene ontology analysis comparing expression profiling of spines and knees in proteoglycan induced spondylitis (PGISp) mice showed a greater number of muscle-associated pathways upregulated in the knee joints suggesting this may be a unique feature of peripheral disease [ 33].
These results suggest that LC3 accumulation is a unique feature following the loss of Fis1 or TBC1D15 and is not caused by defects in mitochondrial fission, consistent with the finding that Fis1 and TBC1D15 do not appear to regulate mitochondrial morphology.
This observation suggests that the SAM domain, a unique feature of p63 and p73 but not p53, is dispensable for the epidermal cell fate and stratification inducing properties of p63 – a finding that is further substantiated by the lung squamous metaplasia phenotype of the SpC-ΔNp63β transgenic animals.
Thus, it can be suggested that the RQC domain, a unique feature of RecQ helicases, may be a key structural element regulating enzymatic activity of this class of helicases.
