Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 70 kDa (predicted molecular weight: 264 kDa).


  • Function

    This is probably a cell growth or differentiation factor receptor with a tyrosine-protein kinase activity.
  • Tissue specificity

    Expressed in brain. Expression is increased in primary gliomas.
  • Involvement in disease

    Note=A chromosomal aberration involving ROS1 is found in a glioblastoma multiforme sample. An intra-chromosomal deletion del(6)(q21q21) is responsible for the formation of GOPC-ROS1 chimeric protein which has a constitutive receptor tyrosine kinase activity.
  • Sequence similarities

    Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
    Contains 9 fibronectin type-III domains.
    Contains 1 protein kinase domain.
