The immunogen of ab124686 is, according to BLAST results, conserved (57%) with human MEIS2. According to this, the antibody might cross-react with MEIS2 but this has, to our knowledge, not been experimentally tested so far.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/10000 - 1/50000. Detects a band of approximately 47 kDa (predicted molecular weight: 43 kDa).
1/10 - 1/100.
Is unsuitable for Flow Cyt,ICC or IHC-P.
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.
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.
Belongs to the TALE/MEIS homeobox family. Contains 1 homeobox DNA-binding domain.
