    Summary
    Enables boss receptor activity. Involved in germ-line stem-cell niche homeostasis and sevenless signaling pathway. Located in plasma membrane. Is expressed in several structures, including adult head; eye disc posterior to the morphogenetic furrow; eye photoreceptor cell; imaginal disc; and photoreceptor precursor cell. Orthologous to human ROS1 (ROS proto-oncogene 1, receptor tyrosine kinase). [provided by Alliance of Genome Resources, Dec 2024]
