Final answer:
Phosphorylated Hid's inability to inactivate IAPs interrupts the apoptosis process, potentially leading to uncontrolled cell proliferation and various cellular disorders.
Step-by-step explanation:
When Hid is phosphorylated, it cannot inactivate IAPs (Inhibitor of Apoptosis Proteins). Normally, active Hid proteins contribute to the process of apoptosis, which is the programmed cell death critical for the development and maintenance of healthy tissues. If Hid is unable to perform its role, IAPs remain active, preventing apoptosis and possibly leading to an accumulation of cells, which could result in tumorigenesis or other cellular disorders.
