Predicted to enable cytokine activity. Predicted to contribute to interleukin-23 receptor binding activity. Predicted to be involved in several processes, including positive regulation of cytokine production; positive regulation of lymphocyte activation; and positive regulation of peptidyl-tyrosine phosphorylation. Predicted to act upstream of or within T cell proliferation and positive regulation of transcription by RNA polymerase II. Predicted to be located in extracellular space. Predicted to be part of interleukin-23 complex. Orthologous to human IL23A (interleukin 23 subunit alpha). [provided by Alliance of Genome Resources, Apr 2022]
