Predicted to enable hormone activity and prolactin receptor binding activity. Predicted to be involved in several processes, including positive regulation of lactation; positive regulation of pri-miRNA transcription by RNA polymerase II; and positive regulation of receptor signaling pathway via JAK-STAT. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in extraembryonic component and reproductive system. Human ortholog(s) of this gene implicated in carotid artery disease. Orthologous to human PRL (prolactin). [provided by Alliance of Genome Resources, Apr 2022]
