Western blot of Ubinuclein-1 + Ubinuclein-2 in MOLT4 lysate was performed using 35ug protein in RIPA buffer. Lysates were probed with a Ubinuclein-1 + Ubinuclein-2 polyclonal antibody (Product# PA5-37942) at a dilution of 1ug/ml and incubated for 1 hour, followed by chemiluminescent detection.

Ubinuclein 1 (UBN1) is a ubiquitously expressed evolutionarily conserved protein which binds to proliferation-promoting genes that are repressed by formation of senescence-associated heterochromatin foci (SAHF). Ubinuclein 1 associates with various transcription factors and with histone methyltransferase activity, is indispensable for SAHF formation and appears to be a regulator of senescence. Although in most cells ubinuclein is localized to the nucleus, in cells forming tight junctions it is recruited to the cell adhesion complexes, dependently on the cell density.
