Enables growth factor activity. Involved in several processes, including cellular response to lipopolysaccharide; negative regulation of neuron death; and response to ethanol. Located in extracellular space. Biomarker of cystitis; lung disease; and middle cerebral artery infarction. Human ortholog(s) of this gene implicated in several diseases, including allergic cutaneous vasculitis; artery disease (multiple); ischemia (multiple); leukemia (multiple); and lung disease (multiple). Orthologous to human CSF3 (colony stimulating factor 3). [provided by Alliance of Genome Resources, Apr 2022]
