TissueNA
Tissue SpecificityIsoform 1 is expressed in hematopoietic lineages with a strong expression in CD4 and CD8 T-lymphocytes. It is also widely expressed in nonhematopoietic tissues. Isoform 5 is expressed only in nonhematopoietic tissues. Isoform 4 is expressed in pancreatic alpha cells. {ECO:0000269|PubMed:17182843, ECO:0000269|PubMed:18266782, ECO:0000269|PubMed:18812475}.
