| Tissue Specificity | Widely expressed with high levels in lymph node and spleen. High expression found in T lymphocytes, including CD4 and CD8-positive T-cells, and monocytes. Very low expression levels in B-lymphocytes. |
| Function | Plays a role in T lymphocyte development and the optimal generation of CD4/CD8 double-positive thymocytes. Inhibitor of GSK3A, possibly by sequestering GSK3A in cytoplasmic vesicles and impairing its translocation to the nucleus. Consequently, impairs GSK3A-dependent transcriptional program and regulation of the DNA damage response occurring during T cells proliferation. Required for the survival of peripheral T cells, natural killer (NK) and NK T-cell development and the maintenance of normal liver function. May promote the survival of mature T lymphocytes upon cytokine withdrawal. May regulate Ca(2+) homeostasis by modulating lysosomal Ca(2+) stores, preventing its accumulation in the absence of T cell activation. May play a role in mitochondrial DNA segregation in hematopoietic tissues. Is a regulator of liver endothelial cell homeostasis. |
