GeneCards Summary for MIB2 Gene

MIB2 (Mindbomb E3 Ubiquitin Protein Ligase 2) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include actin binding and signal transducer activity. An important paralog of this gene is ANKDD1B.

UniProtKB/Swiss-Prot for MIB2 Gene

  • E3 ubiquitin-protein ligase that mediates ubiquitination of Delta receptors, which act as ligands of Notch proteins. Positively regulates the Delta-mediated Notch signaling by ubiquitinating the intracellular domain of Delta, leading to endocytosis of Delta receptors (By similarity).

Function for MIB2 Gene

Molecular function for MIB2 Gene

UniProtKB/Swiss-Prot Function: E3 ubiquitin-protein ligase that mediates ubiquitination of Delta receptors, which act as ligands of Notch proteins. Positively regulates the Delta-mediated Notch signaling by ubiquitinating the intracellular domain of Delta, leading to endocytosis of Delta receptors (By similarity).
UniProtKB/Swiss-Prot Induction: Down-regulated in many primary skin melanomas. Treatment with a demethylating agent, 5-aza-2-deoxycytidine, restores expression, suggesting that down-regulation is the result of methylation of the gene.
