Several cathepsin L transcripts, including FhCatL5, have been isolated from adult Fasciola, while certain cathepsin L proteases, including FgCatL1G, have only been identified in the juvenile forms of the parasite.
The article explains that in the Aquitaine region of France, the species' native home, 25 species of worm have only been identified in that region, and never anywhere else.
She added: "Previously these cases have only been identified in two other countries worldwide.
CitMHS family members transport metal citrate complexes in symport with a proton, and have only been identified in bacteria thus far.
They have only been identified in inflamed skin where they promote wound repair and mediate the systemic pro-inflammatory response that is seen after stimulation with Toll-like receptor 7 (TLR7) agonists (Gregorio et al., 2010).
Gregg Smith, public affairs officer for the weapons station, said the base's construction funds have only been identified as a potential source of border wall funding.
Systemins have only been identified in the Solaneae subtribe of the Solanaceae, but other members of the family, such as tobacco, also respond to wounding by systemically producing protease inhibitors.
As ICRs have only been identified for seven imprinted clusters [31], the Rasgrf1 system provides an uncommon opportunity to study regulation of imprinted gene expression.
At present, secretin and its receptor have only been identified in mammals, and the origin of this ligand-receptor pair in early vertebrates is unclear.
Both outcrossing and selfing has been described in T. brucei in laboratory crosses [40], [41], but the products of selfing have only been identified when cross fertilisation occurs, and not observed when a single strain is used to infect tsetse.
In contrast, additional mitochondrial protein-coding genes, usually found in mtDNAs of the closest unicellular relatives of animals (e.g., mutS, dnaB, atp9, tatC in protists), have only been identified and annotated in the mitochondrial genomes of non-bilaterian animals (i.e., Cnidaria and Porifera; [3]).
