UniProt curated annotations — full annotation on UniProt →

Function. May play a role in protection against oxidative stress. Overexpression leads to reduced levels of oxidant-induced DNA damage and apoptosis.

Subcellular location. Membrane.

Induction. Up-regulated in cells which display transient adaptation to mild oxidative stress by treatment with diethylmaleate, a glutathione-depleting agent. Also induced by retinoic acid.

Similarity. Belongs to the TMEM161 family.

PubChem BioAssay actives

2 with measured affinity, of 4 total; 2 most potent distinct compounds. Largely complementary to BindingDB; screening values are coarse (µM, 4 dp), so sub-nM hits tie at the floor.
