Recombinant fragment (with 26 kDa tag): EAIQAVADRL QRQEEERMNC SPTSQIDNIG EEEMDASTTH HKRKTMNDFD YLKLLGKGTF GKVILVREKA SGKYYAMKIL KKEVIIAKDE , corresponding to amino acids 100-189 of Human AKT3 (AAD29089) (sequence does not include tag)
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 5 µg/ml. Predicted molecular weight: 56 kDa.
Use at an assay dependent dilution.
FunctionIGF-1 leads to the activation of AKT3, which may play a role in regulating cell survival. Capable of phosphorylating several known proteins. Truncated isoform 2/PKB gamma 1 without the second serine phosphorylation site could still be stimulated but to a lesser extent.
Tissue specificityIn adult tissues, it is highly expressed in brain, lung and kidney, but weakly in heart, testis and liver. In fetal tissues, it is highly expressed in heart, liver and brain and not at all in kidney.
Sequence similaritiesBelongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. RAC subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 1 PH domain. Contains 1 protein kinase domain.
DomainBinding of the PH domain to the phosphatidylinositol 3-kinase alpha (PI(3)K) results in its targeting to the plasma membrane.
Post-translational modificationsPhosphorylation on Thr-305 and Ser-472 is required for full activity (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR. Ubiquitinated. When fully phosphorylated and translocated into the nucleus, undergoes 'Lys-48'-polyubiquitination catalyzed by TTC3, leading to its degradation by the proteasome.
Cellular localizationCytoplasm. Membrane. Membrane-associated after cell stimulation leading to its translocation.
