Function

ETT1_SCHPO Required for correct translation termination (By similarity). Positive regulator of the stability of the N-terminal transcription factor domain (Sre1N) of sre1 which is released from the membrane and enters the nucleus to activate hypoxic gene expression. Acts also as a direct inhibitor of ofd1. Functions probably by inhibiting the ability of the ofd1 to accelerate Sre1N degradation in absence of oxygen.^[1] ^[2]
