The phrase "assembling factor" is correct and usable in written English.
It can be used in contexts where you are referring to a component or element that contributes to the process of assembling something, such as in manufacturing or project management.
Example: "The assembling factor in our production line has significantly improved efficiency and reduced errors."
Alternatives: "assembly component" or "construction element".
We reasoned that if Pbx proteins, as pioneer factors, play a necessary role in assembling factors to drive fast-muscle gene expression, then expression of fast muscle genes should be reduced and delayed in pbx2/4-MO; prdm1a−/− embryos, as in pbx2/4-MO embryos.
Thus, whereas DSB ends and ssDNA are necessary to establish a platform to assemble factors required for the localized activation of the checkpoint and for the repair of the damage, a widespread and efficient DNA damage response which should be turned off when repair is complete takes advantage of DNA species that are only produced while repair is ongoing.
Under similar experimental conditions, prothrombinase assembled with factor VaFF/KF, factor VaMI/KF, factor VaFF/AA, and factor VaMI/AA did not activate prothrombin to any significant extent, following a 3 h incubation period (data not shown).
The data shown in Figures 5− 8 demonstrate that prothrombinase assembled with factor VaΔ659−663, factor Va5K, and factor Va5A (under conditions that would promote activation of prothrombin exclusively through the meizothrombin pathway) are impaired in their ability to support the initial cleavage of prothrombin at Arg.
These results indicate that substitution of amino acids 334 and 335 of the factor Va heavy chain results in delayed prothrombin activation by factor Xa within prothrombinase assembled with factor VaKF or factor VaAA.
Of all the assembling factors that eventually send debris flows rumbling down the canyons, none is more detonative than the waterproof soil.
Kinetic studies showed that while factor VaKF and factor VaAA had a KD for factor Xa similar to the KD observed for wild-type factor Va (factor VaWT), the clotting activities of the mutant molecules were impaired and the kcat of prothrombinase assembled with factor VaKF and factor VaAA was reduced.
It is important to note that the maximum increase in the rate of cleavage of meizothrombin at Arg by prothrombinase assembled with factor VaPLASMA or factor VaWT as compared to cleavage of the molecule by factor Xa alone is 4-fold (3, 40).
Similar results were found with prothrombinase assembled with factor VaKF/4A and factor Va6A.
