  • General notes

    PRAME (PReferentially expressed Antigen in MElanoma) is a tumor-associated antigen and is a member of the family of cancer testis antigens (CTA). PRAME is expressed in malignant cells, including leukaemias, Hodgkin's lymphoma, breast cancer, and primary and metastatic melanomas. For more information, please refer to PMID: 27441500. PRAME has low or no expression in normal tissues except for in testis, ovary, placenta, adrenals and endometrium. For more information, please refer to PMID: 9047241.

    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMab® patents.

Target

  • Function

    Functions as a transcriptional repressor, inhibiting the signaling of retinoic acid through the retinoic acid receptors RARA, RARB and RARG. Prevents retinoic acid-induced cell proliferation arrest, differentiation and apoptosis.
  • Tissue specificity

    Expressed in testis. Detected in samples of kidney, brain and skin.
  • Sequence similarities

    Belongs to the PRAME family.
    Contains 4 LRR (leucine-rich) repeats.
