  • Primary antibody notes

    The munc-18 interacting (Mint) protein family is a group of evolutionarily conserved adaptor proteins that function in membrane transport and organization. In mammals, there exist three Mint isoforms, Mint 1, 2, and 3. Although there is little amino acid sequence conservation in the amino-terminal half, the carboxy-terminal half of these proteins is highly conserved. Within this conserved portion there exists a phosphotyrosine-binding (PTB) and a PSD-95/DLG-A/ZO-1 (PDZ) domain, which function as protein interaction modules. Mint 1 and 2 appear to be expressed exclusively in the brain and are found to bind to Munc18, an essential component of the synaptic vesicle fusion machinery. Mint 3 is ubiquitously expressed in all tissues and is expressed at the lowest levels in the brain and testis. Studies show that Mint3 does not interact with munc-18. Mint 3 has been found to interact with the Alzheimer’s Disease-related amyloid precursor protein (APP) and does so through its PTB and PDZ domains. It has been suggested that Mint3 links APP to other transport machinery components, thereby regulating it transport, endocytosis, and metabolism. Abnormal APP metabolism has been shown to be the cause of an early-onset type of Alzheimer’s disease.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 130 kDa (predicted molecular weight: 93 kDa).

By Western blot, this antibody detects an ~130 kDa protein representing Mint 1 from rat forebrain postnuclear supernatant.


  • Function

    Putative function in synaptic vesicle exocytosis by binding to Munc18-1, an essential component of the synaptic vesicle exocytotic machinery. May modulate processing of the beta-amyloid precursor protein (APP) and hence formation of beta-APP.
  • Tissue specificity

    Brain and spinal cord.
  • Sequence similarities

    Contains 2 PDZ (DHR) domains.
    Contains 1 PID domain.
  • Domain

    Composed of an N-terminal domain that binds Munc18-1 and LIN-2/CASK, a middle phosphotyrosine-binding domain (PID/PTB) that mediates binding with the cytoplasmic domain of the beta-amyloid precursor protein, and two C-terminal PDZ domains thought to attach proteins to the plasma membrane.

Customer reviews and Q&As


Thank you for your enquiry. Ab 3448 has been tested for cross-reactivity with rat, and has not yet been tested for cross-reactivity in other species. We do not know if Ab3448 will give a single band on chick brain extract. Should you decide to go ahead and purchase this product, please let us know how you get on and in return we will forward a reward of your choice, typically an Amazon gift voucher.
