ROS1

Chr 6

ROS proto-oncogene 1, receptor tyrosine kinase

Also known as: MCF3, ROS, c-ros-1

This proto-oncogene, highly-expressed in a variety of tumor cell lines, belongs to the sevenless subfamily of tyrosine kinase insulin receptor genes. The protein encoded by this gene is a type I integral membrane protein with tyrosine kinase activity. The protein may function as a growth or differentiation factor receptor.
