There are two human genes that encode otubain proteins: OTUB1 and OTUB2 [1]. They are deubiquitinases that are classified within the C65 family of cysteine proteases in the MEROPS system.

compound 61 [PMID: 36221183] pIC50 9.8 [3]
Comment A cysteine protease with deubiquitinase activity that cleaves ubiquitin from branched poly-ubiquitin chains, but not from ubiquitinated proteins. Predicted to promote immune evasion (likely via inhibiting cytokine gene transcription and immune cell functions in the tumour microenvironment) and tumourigenesis, and is therefore a molecular target for anti-tumour drug discovery [2-3].
