TissueNA
Tissue SpecificityUbiquitous. Highly expressed in spleen and leukocytes. Generally the expression of isoform 1 is higher than that of isoform 2. Isoform 2 is particularly abundant in testis and brain. In testis, isoform 1 is detected in spermatogonia at different stages and absent from Sertoli cells, while isoform 2 is present in both (at protein level). Expressed in the choroid plexus epithelium, isoform 1 being localized at the basolateral membrane and isoform 2 at the apical one, as well as in the subapical intracellular vesicular compartments. Differential expression of both isoforms is also observed in other brain region: isoform 1 is very abundant in the gray matter of the frontal cortex, but is not associated with neuronal cell bodies. Not detected in the white matter. In contrast, isoform 2 is associated with neuronal bodies and axons in both the gray and the white matters of the frontal cortex. Expressed in placental trophoblasts (PubMed:10873595, PubMed:12409283). Expressed in pancreas, kidney, liver, lung, brain, heart, peripheral blood leukocyte, colon, small intestine, ovary, testis, prostate, thymus and spleen. Expressed in fetal brain, heart, kidney, liver, lung, skeletal muscle, spleen and pancreas (PubMed:10873595). {ECO:0000269|PubMed:10873595, ECO:0000269|PubMed:12409283, ECO:0000269|PubMed:16971491}.
