Mouse Microtubule-associated protein RP/EB family member 3 (MAPRE3) ELISA Kit

MAPRE3 is a member of the RP/EB family of genes. The protein localizes to the cytoplasmic microtubule network and binds APCL, a homolog of the adenomatous polyposis coli tumor suppressor gene. The predicted 282-amino acid protein is 54% identical to MAPRE1. Northern blot analysis revealed expression of a 2.2-kb transcript predominantly in brain and muscle. GST pull-down analysis determined that a homologous region in the C termini of APC and APCL binds to MAPRE3. Immunofluorescence and confocal microscopy demonstrated that MAPRE3 is localized in the microtubule network and colocalizes with APCL in the perinucleus and microtubule network.
