 Use of CD 161


CD161 is a potent and orally bioavailable bromodomain and extra-terminal (BET) bromodomain inhibitor with an IC50 of 28.2 nM and a Ki of 8.2 nM for BRD4 BD1[1]. CD161 is a C-type lectin-like receptor expressed on the majority of natural killer (NK) cells. CD161 demonstrates high selectivity over 24 non-BET proteins containing bromodomains[2].
