Application Abreviews Notes
WB 1/750. Detects a band of approximately 180 kDa.


  • FunctionIn case of filovirus infection, seems to function as a cell entry factor.
  • Tissue specificityNot expressed in normal B- and T-lymphocytes but is expressed in numerous neoplastic B- and T-cell lines.
  • Involvement in diseaseDefects in MERTK are the cause of retinitis pigmentosa type 38 (RP38) [MIM:613862]. RP38 is a retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. AXL/UFO subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 protein kinase domain.

Thanks for the information.

The results are very strange. I am sorry I could not find a good reason why the antibodies are showing difference. Technically, they should show the same band size. The MERTK protein is heavily glycosylated so 180 k...
