| Tissue Specificity | Expressed in bile canaliculi in liver, in bronchiolar epithelium in lung and in tubular structures of gland ducts inside the olfactory epithelium and tongue epithelium. |
| Function | Acts as a novel regulator of senescence. Involved in the formation of senescence-associated heterochromatin foci (SAHF), which represses expression of proliferation-promoting genes. Binds to proliferation-promoting genes. May be required for replication-independent chromatin assembly. |
