Although many characters clearly characterize the Archaea as a group that is distinct from the Bacteria (2), recent complete genome analyses confirm earlier observations that many (44%) archaeal genes are very similar to their bacterial homologs
, whereas only 13% are more similar to their eukaryotic homologs
of the fork head/HNF-3[Beta] class of genes play a central role in organizing the development of the rostral part of vertebrate heads, as well as the notochord (e.
Apart from their suggested role in the hypothalamus, the vertebrate lin-11 and ttx-3 homologs
Lhx1 and Lhx2 are expressed in several additional places in the nervous system (9, 10).
Our analyses indicate that cnidarians may possess homologs
to posterior members of the complex as well as to the more anterior genes.
coli mscL, (2) elucidating the function of these MS channels in bacterial physiology, and (3) searching for mscL homologs
in other species, including plants and animals.
magnifica the type of latrunculin homologs
is, however, a solid character with which to distinguish between different populations.
A phylogenetic tree consisting of BmARM-like protein and 13 other homologs
Two remote homologs
are proteins that belong to the same superfamily but at the same time they belong to different families, which means they have the same function but also a low sequence identity.
In this study, a comparative genomics approach was employed to identify Arabidopsis thaliana homologs
of yeast genes involved in UPR.
Using the sequences of CO and HD1 as models, many CONSTANS homologs
genes have been identified in different plant species including wheat (Triticum aestivum) (Nemoto, 2003), eastern cottonwood (Populus deltoides) (Yuceer et al.
1] and its homologs
, Section II-aspartic peptidases: pepsin, nepenthesin and their homologs
, Section III-glutamic peptidases: aspergilloglutamic peptidase and its homologs
and Section IV-serine-carboxyl peptidases: physarolisins I and II and their homologs
They are suggested to play an important role in nuclear envelope organization and cell cycle control, as has been shown for lamina-associated polypeptides 2 alpha and beta, which are the rat homologs
of human TMPOalpha and TMPObeta, respectively.
These soluble homologs
of the ligand binding domain of nicotinic receptors have proven tremendous utility in this study offering robust high throughput screening of natural products and compound libraries.
Furthermore, a previous study compared miRNAs identified in the rhesus macaque (Macaca mulatta) genome to human homologs
and found that 38% of the miRNAs showed 100% homology in precursor sequences (Yue et al.
Among the 98 flowering-related genes identified, the homologs
of a floral pathway integrator, SbFT, and a floral repressor, SbSVP, showed dramatic transcriptional changes before flowering, and their flowering functions were confirmed using transgenic Arabidopsis thaliana.
