Prlr Gene Summary [Rat]
Enables prolactin receptor activity and protein kinase binding activity. Involved in cellular response to granulocyte macrophage colony-stimulating factor stimulus; positive regulation of B cell proliferation; and positive regulation of protein autophosphorylation. Predicted to be located in cell surface. Predicted to be part of receptor complex. Predicted to be active in external side of plasma membrane. Human ortholog(s) of this gene implicated in hyperprolactinemia. Orthologous to human PRLR (prolactin receptor). [provided by Alliance of Genome Resources, Jul 2025]
