DNA/RNA
Note
There are at least six alternative splicing forms.

Genomic structure of Mib2/skeletrophin
Description
20 Exons spanning 14kb on 1p36.33.
Proteins
Note
The number of amino acids are varied in each splicing form.

Schematic illustrating of mib2/skeletrophin.
Expression
Human mib2/skeletrophin is strongly expressed in adult brain, heart and skeletal muscles.
Localisation
Cytoplasmic
Function
Ubiquitin ligase to cytoplasmic domain of Notch ligands and NMDA receptor GRIN2B/NR2B subunit. Putative positive regulation of I-kappaB kinase/NF-kappaB cascade.
Homology
The protein structure of mib2/skeletrophin is closely related to MIB1 (mind bomb-1 homolog).
Implicated in
Entity name
Multiple myeloma, especially at advanced stage with osteolytic lesion.
Oncogenesis
Putative oncogenic factor for multiple myeloma thorough bone marrow microenvironments. In multiple myeloma, Mib2/skeletrophin and its substrates, Jagged-1 and Jagged-2, are both overexpressed in bone marrow microenvironments. Ligands-dependent Notch activation is occurred by direct cell-cell interaction between multiple myeloma cells and bone marrow stromal cells and contribute the myeloma niche, which is known as microenvironment suitable for myelomagenesis.
