Genes affected

MIB2 (HGNC:30577): (MIB E3 ubiquitin protein ligase 2) The protein encoded by this gene is an E3 ubiquitin protein ligase that mediates ubiquitination of proteins in the Notch signaling pathway. The encoded protein may be a suppressor of melanoma invasion. [provided by RefSeq, Mar 2017]
