Target
-
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. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-ROS1 antibody [EPMGHR2] (ab189925)
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung carcinoma tissue sections labeling ROS1 with Purified ab189925 at 1:300 dilution (5.23 μg/ml). Heat mediated antigen retrieval was performed using EDTA Buffer, pH9.0. Tissue was counterstained with hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control.
