The function of Ensembl gene identifier ENSG00000008853 (RHOBTB2, Rho related BTB domain containing 2) is as follows. Regulator of cell proliferation and apoptosis (PubMed:21801820). It likely functions as a substrate-adapter that recruits key substrates, e.g. MSI2, to CUL3-based ubiquitin ligase complexes for degradation (PubMed:15107402, PubMed:27941885). Required for MSI2 ubiquitination and degradation (PubMed:27941885). {ECO:0000269|PubMed:15107402, ECO:0000269|PubMed:21801820, ECO:0000269|PubMed:27941885}.
