COMMENT     VALIDATED REFSEQ: This record has undergone validation or
            preliminary review. The reference sequence was derived from
            AL731772.9.
            
            Summary: This gene encodes a secreted growth factor that belongs to
            the pleiotrophin/midkine heparin-binding protein family and
            functions in a variety of biological processes. The encoded
            cytokine promotes the growth, differentiation, survival and
            migration of several target cells including leucocytes involved in
            inflammation. This protein plays a role in the formation of scar
            tissue and intraperitoneal adhesions, and promotes neurite
            outgrowth and neuron survival. The protein encoded by this gene is
            associated with obesity and inhibition of insulin signaling in fat
            cells. A pseudogene of this gene is present on chromosome 11.
            Alternative splicing results in multiple transcript variants.
