Hypotheses on this target 1
Inhibition1
Activation
Lower level
Higher level
Replacement
Protection from degradation
Cofactor removal
Synthesis suppression
Function preservation
Inhibition1
Estradiol may directly boost activated factor XIII and prolong clotting risk
Where this hypothesis actsPurified, preactivated protein at free estradiol concentrations measured in menopausal-treatment participants
What is proposedPrevent estradiol potentiation while preserving basal catalysis
With whatNot stated in the record
HowIdentify and alter the estradiol binding site, then test soluble-substrate turnover and binding with orthogonal measurements
Possible resultExpected loss of estradiol-induced excess enzyme activity with basal catalysis preserved
