Predicted to enable transmembrane receptor protein tyrosine kinase activity. Involved in phagocytosis; positive regulation of phagocytosis; and protein phosphorylation. Located in photoreceptor outer segment. Used to study retinal degeneration. Human ortholog(s) of this gene implicated in retinitis pigmentosa 38. Orthologous to human MERTK (MER proto-oncogene, tyrosine kinase). [provided by Alliance of Genome Resources, Apr 2022]
