Tissue SpecificityIsoform 1 and isoform 2 are expressed in lung, stomach, spleen, heart and skin;
in these tissues, isoform 1 is predominant. Isoform 2 is expressed in aorta, spleen, and breast tumor, with highest levels in the endothelial cells of some blood vessels surrounding the aorta, as well as those surrounding the tumor and low levels, if any, in mast cells (at protein level). {ECO:0000269|PubMed:18854315}.
