CC -!- TISSUE SPECIFICITY: Expressed in several tissues including thymus,
CC spleen, liver, kidney, small and large intestine, testis and placenta.
CC Expressed by oligodendrocytes, B-cells and macrophages but not
CC granulocytes, T-cells or NK cells (at protein level).
CC {ECO:0000269|PubMed:11062505, ECO:0000269|PubMed:12527391}.
