Disease:Chromosomal aberrations activating TCL1A are found in chronic T-cell leukemias (T-CLL) . Translocation t (14;14) (q11;q32) ; translocation t (7;14) (q35;q32) ; inversion inv (14) (q11;q32) that involves the T-cell receptor alpha/delta locuses. ,Function:Enhances the phosphorylation and activation of AKT1 , AKT2 and AKT3. Promotes nuclear translocation of AKT1. Enhances cell proliferation , stabilizes mitochondrial membrane potential and promotes cell survival. ,similarity:Belongs to the TCL1 family. ,subcellular location:Microsomal fraction. ,subunit:Homodimer. Interacts with AKT1 , AKT2 and AKT3 (via PH domain) . Interacts with PNPT1; the interaction has no effect on PNPT1 exonuclease activity. ,tissue specificity:Restricted in the T-cell lineage to immature thymocytes and activated peripheral lymphocytes. Preferentially expressed early in T- and B-lymphocyte differentiation. ,
