The phrase "absence pathway" is correct and usable in written English.
It can be used in contexts related to biology, psychology, or any field discussing the mechanisms or routes associated with absence or lack of something.
Example: "Researchers are studying the absence pathway in the brain to understand how it affects memory loss."
Alternatives: "lack pathway" or "absence route".
In absence of pathway activation, they recruit proteins that establish repression at target sites, whereas when the pathway is active, they associate with β-catenin to activate target gene expression.
Deletion of MPT5 derepresses the fMAPK output reporter by 16-fold in the absence of pathway stimuli (Fig. 6).
In the absence of pathway activation by WNT ligands or small molecule inhibitors of GSK3, β-catenin is sequentially phosphorylated by CK1 and GSK3β[4].
The presence or absence of pathways of interest was determined by BLAST searches of reference sequences and HMM searches of reference Pfam profiles against the T. roseum proteome.
The Kyoto Enzyclopedia of Genes and Genomes (KEGG) is a valuable resource to evaluate the presence or absence of pathways.
The large extent of variation in gene content between related bacterial genomes suggests a corresponding variation in gene presence and absence within pathways.
Protein sequences of all other species included in this study were also analyzed using the KAAS server and the presence and absence of pathways were tested using shell and perl scripts.
Two heatmaps were generated: (i) for the first heatmap, we used the completeness values that range from 0 to 1 as an approximate binary estimate of the presence or absence of pathways.
The totally absence of this pathway in amitochondriate protists (without any enzymes of this pathway) is consistent with the lack of typical mitochondria and CL in these protists, and must be due to the degeneration of mitochondria in them.
While there is evidence of a PERK-based translational UPR in Toxoplasma gondii [11], the apparent absence of this pathway in T. brucei makes it difficult to assume that this pathway exists in other protozoan parasites.
They've said they won't take on new legally binding commitments in the absence of a pathway that sees the US, China, Japan, Russia, and other big emitters restraining their own emissions in a reasonable timeframe.
