Hematopoietic growth factor capable of stimulating the proliferation of lymphoid progenitors. It is important for proliferation during certain stages of B-cell maturation. Belongs to the IL-7/IL-9 family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
