The phrase "activate expression" is correct and usable in written English.
It can be used in contexts where you want to initiate or enable a specific expression, such as in programming or artistic contexts.
Example: "To see the changes in the animation, you need to activate expression in the software settings."
Alternatives: "enable expression" or "trigger expression".
Similar to Pax6 deficient mice, MafB deficient mice showed reductions both in insulin and glucagon expressing cells and in the ability of MafB and PDX-1 expressing cells to activate expression of these hormones.
The Myb2 transcription factor is able to complement Arabidopsis thaliana trichome mutants and activate expression of R22-like (RDL) gene expressed in fiber initials [ 11, 12].
However, Dicer-null NS cells fail to activate expression of a large set of genes expressed during glial differentiation, including GFAP (Fig. 5H).
The activated SnRK2s phosphorylate and activate AREB/ABF/ABI5, and subsequently activate expression of AREB/ABF/ABI5 target genes [15, 18, 36, 86].
This release from latency in the cytoplasm allows active NF-κB to translocate into the nucleus and activate expression of target genes, including several feedback genes [4].
GRQCIMFI is constitutively expressed, and in the presence of ligand can activate expression of a target gene 6-fold.
This activation allows TP53 to recruit another HAT complex (NuA4) and activate expression of its target genes via histone H4 hyperacetylation.
Under non-symbiotic conditions MtD27 is mainly expressed in the stele of the root, whereas rhizobium LCOs activate expression in the root epidermis.
If NHR-64 has transcriptional activity, it will interact with the GALBD to bind the promoter and activate expression of the HIS reporter gene.
Jellyfish PaxB does not activate expression of crystallin genes of other species.
How they selectively activate expression of the pluripotency network while simultaneously repressing genes involved in differentiation is not fully understood.
