Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 73 kDa (predicted molecular weight: 69 kDa).


  • Function
    This is a receptor for the anterior pituitary hormone prolactin (PRL). Isoform 4 is unable to transduce prolactin signaling. Isoform 6 is unable to transduce prolactin signaling.
  • Tissue specificity
    Expressed in breast, placenta, kidney, liver and pancreas.
  • Sequence similarities
    Belongs to the type I cytokine receptor family. Type 1 subfamily.
    Contains 2 fibronectin type-III domains.
  • Domain
    The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
    The box 1 motif is required for JAK interaction and/or activation.
  • Cellular localization
    Secreted and Membrane.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 69 kDa
    Observed band size: 73 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 61 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 2 minutes

    Human Prolactin receptor precursor contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
