Summary
MID2 (midline 2, HGNC:7096) is a protein-coding gene on chromosome Xq22.3, encoding Probable E3 ubiquitin-protein ligase MID2 (Q9UJV3). E3 ubiquitin ligase that plays a role in microtubule stabilization.
The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. The protein localizes to microtubular structures in the cytoplasm. Alternate splicing of this gene results in two transcript variants encoding different isoforms.

All UniProt accessions (2): Q9UJV3, A6PVI4

Function. E3 ubiquitin ligase that plays a role in microtubule stabilization. Mediates the ‘Lys-48’-linked polyubiquitination of LRRK2 to drive its localization to microtubules and its proteasomal degradation in neurons. This ubiquitination inhibits LRRK2 kinase activation by RAB29.
Subunit / interactions. Homodimer or heterodimer with MID1. Interacts with IGBP1.
Subcellular location. Cytoplasm. Cytoskeleton.
Tissue specificity. Low level in fetal kidney and lung, and in adult prostate, ovary and small intestine.
Post-translational modifications. Phosphorylated on serine and threonine residues.
Disease relevance. Intellectual developmental disorder, X-linked 101 (XLID101) [MIM:300928] A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked forms, while syndromic forms present with associated physical, neurological and/or psychiatric manifestations. XLID101 clinical features include global developmental delay, hyperactivity often with aggressive outbursts, and seizures in some patients. Several affected individuals have long face, prominent ears, and squint or strabismus. The disease is caused by variants affecting the gene represented in this entry.
Domain organisation. The tripartite motif (RBCC; RING- and B box-type zinc fingers and coiled coil domains) mediates dimerization. Associates with microtubules in a manner that is dependent on the C-terminal B30.2 domain.
Pathway. Protein modification; protein ubiquitination.
Similarity. Belongs to the TRIM/RBCC family.
