| Plasminogen activators attached to fibrin activate plasminogen, causing the release of the enzyme plasmin within clots and thrombi. |
| This family includes receptors for steroid hormones, thyroid hormones, hormonal forms of vitamin A and D, and peroxisomal activators. |
| The aforementioned findings suggest that immune activators produced anhedonia, or lack of interest in pleasurable stimuli. |
| The only apparent regulatory difference is a short time delay when activators reside in the cytoplasm before binding to plasmids. |
| They may also serve as upstream activators of the protein kinase C, which is involved in cell wall biosynthesis. |
| This analysis also explains why most repressers and activators bind as dimers and tetramers, not trimers or pentamers. |
