Comments
  • FUNCTION: May have E3 ubiquitin ligase activity which targets the catalytic subunit of protein phosphatase 2 for degradation.
  • SUBUNIT: Homodimer or heterodimer with MID2. Interacts with IGBP1.
  • SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton. Note=Microtubule-associated. It is associated with microtubules throughout the cell cycle, co-localizing with cytoplasmic fibers in interphase and with the mitotic spindle and midbodies during mitosis and cytokinesis.
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.
    Name1
    SynonymsAlpha
    Isoform IDO15344-1
    This is the isoform sequence displayed in this entry.
    Name2
    SynonymsBeta
    Isoform IDO15344-2
    Features which should be applied to build the isoform sequence: VSP_005735.
  • TISSUE SPECIFICITY: In the fetus, highest expression found in kidney, followed by brain and lung. Expressed at low levels in fetal liver. In the adult, most abundant in heart, placenta and brain.
  • INDUCTION: A retroviral element acts as an alternative tissue-specific promoter for this gene. The LTR of an HERV-E element enhances the expression in placenta and embryonic kidney.
  • PTM: Phosphorylated on serine and threonine residues.
  • DISEASE: Defects in MID1 are the cause of Opitz syndrome type I (OS-I) [MIM:300000]. OS-I is an X-linked recessive disorder characterized by hypertelorism, genital-urinary defects such as hypospadias in males and splayed labia in females, lip-palate-laryngotracheal clefts, imperforate anus, developmental delay and congenital heart defects. OS-I mutations produce proteins with a decreased affinity for microtubules.
  • SIMILARITY: Belongs to the TRIM/RBCC family.
  • SIMILARITY: Contains 2 B box-type zinc fingers.
  • SIMILARITY: Contains 1 B30.2/SPRY domain.
  • SIMILARITY: Contains 1 COS domain.
  • SIMILARITY: Contains 1 fibronectin type-III domain.
  • SIMILARITY: Contains 1 RING-type zinc finger.
  • WEB RESOURCE: Name=GeneReviews; URL="http://www.genetests.org/query?gene=MID1";.
