Predicted to enable cytokine receptor activity and granulocyte colony-stimulating factor binding activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; monocyte differentiation; and positive regulation of tyrosine phosphorylation of STAT protein. Predicted to act upstream of or within acute inflammatory response to antigenic stimulus; defense response to other organism; and glandular epithelial cell differentiation. 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 primary localized cutaneous amyloidosis 2. Orthologous to human IL31RA (interleukin 31 receptor A). [provided by Alliance of Genome Resources, Apr 2022]
