Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 44 kDa (predicted molecular weight: 43 kDa).
IP 1/200 - 1/2000.
IHC-P 1/20 - 1/200.


  • Function

    Acts as a transcriptional regulator of PAX6. Acts as a transcriptional activator of PF4 in complex with PBX1 or PBX2. Required for hematopoiesis, megakaryocyte lineage development and vascular patterning. May function as a cofactor for HOXA7 and HOXA9 in the induction of myeloid leukemias.
  • Tissue specificity

    Expressed at low level in normal immunohepatopoietic tissues, including the fetal liver. Expressed in a subset of myeloid leukemia cell lines, with the highest expression seen in those with a megakaryocytic-erythroid phenotype. Also expressed at high levels in the cerebellum.
  • Involvement in disease

    Defects in MEIS1 could be a cause of susceptibility to restless legs syndrome type 7 (RLS7) [MIM:612853]. Restless legs syndrome (RLS) is a neurologic sleep/wake disorder characterized by uncomfortable and unpleasant sensations in the legs that appear at rest, usually at night, inducing an irresistible desire to move the legs. The disorder results in nocturnal insomnia and chronic sleep deprivation.
  • Sequence similarities

    Belongs to the TALE/MEIS homeobox family.
    Contains 1 homeobox DNA-binding domain.

  • Paraffin-embedded human prostate cancer tissue stained for MEIS1 using ab229962 at 1/100 dilution in immunohistochemical analysis.

  • MEIS1 was immunoprecipitated from 0.5 mg K562 (human chronic myelogenous leukemia cell line from bone marrow) whole cell lysate with 4 µg ab229962. Western blot was performed from the immunoprecipitate using ab229962. HRP-conjugated Protein G antibody was used as the secondary antibody at 1/50000 dilution.

    Lane 1: 1 µg Rabbit monoclonal IgG instead of ab229962 in K562 whole cell lysate.
    Lane 2: ab229962 IP in K562 whole cell lysate.
    Lane 3: K562 whole cell lysate 20 µg (Input).
