Mib1 Antibody / Mindbomb

E3 ubiquitin-protein ligase MIB1 is an enzyme that in humans is encoded by the MIB1 gene. It is mapped to 18q11.2. This gene encodes a protein containing multiple ankyrin repeats and RING finger domains that functions as an E3 ubiquitin ligase. The encoded protein positively regulates Notch signaling by ubiquitinating the Notch receptors, thereby facilitating their endocytosis. This protein may also promote the ubiquitination and degradation of death-associated protein kinase 1 (DAPK1).
