Protein Function and Prediction

MIB2 is an E3 ligase that is associated with several signaling pathways including Notch and glutamate receptor signaling as well as muscle stability in Drosophila (1-4).  MIB2 has also been identified as a component of the activated B-cell CLL/lymphoma 10 (BCL10) complex (5). BCL10 is involved in the activation of NF-κB in both the T-cell receptor (TCR) and B-cell receptor pathways through the promotion of the autoubiquitination and ubiquitination of IKKγ/NEMO, as well as recruitment and activation of TAK1 (5).

Expression/Localization

Northern blot analysis detected a highly expressed transcript in skeletal muscle; lower expression of the transcript was detected in brain, heart, and kidney (6).  In another study, Mib2 expression appears to be equal throughout development and in all adult tissues (7). Western blot analysis detected the protein in skeletal muscle, heart, and brain, but not in liver, thymus, or lung (6). Mib2 is localized in cytoplasmic foci near the cell surface (6).

Background

Mib2tm1Art/tm1Art; MGI:3652500

BTNTTFArt.129S6-Mib2tm1Art

Mice homozygous for a knock-out allele display exencephaly with a variable penetrance that depends on the genetic background (7).

 

Mib2tm1Kong/tm1Kong; MGI:3804450

involves: 129P2/OlaHsd * C57BL/6

Mice homozygous for a reporter/null allele are viable, fertile and show normal growth, body weight and brain morphology (8).
