Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Specificity / Sensitivity
MIB1 Antibody detects endogenous levels of total MIB1 protein. This antibody does not recognize the Ki-67 (MK167) protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human MIB1 protein. Antibodies were purified by protein A and peptide affinity chromatography.
Mindbomb homolog 1 (MIB1) is an E3 ligase that facilitates the ubiquitination and the subsequent endocytosis of the Notch ligands, Delta and Jagged (1,2). MIB1 appears to promote the ubiquitination and degradation of death-associated protein kinase (DAPK1) in vitro (3). Expression of MIB1 is seen in both adult and embryonic murine tissues (4). Recently, MIB1 was reported to regulate the extrinsic cell death pathway by binding to cellular FLICE-like inhibitory proteins (cFLIP-L and cFLIP-S), which reduces the interaction of caspase-8 with cFLIP and leads to cell death (5). MIB1 is also involved in T and marginal zone B (MZB) cell development in the lymphopoietic niches (6).
