Reprogramming mouse fibroblast cell to iPS cells using 3 retroviral vectors, which carry Oct4, Sox2 & Klf4 with this protein as replacement assay. 8 μg/ml of human Klf4-11R were added in reprogramming medium every 48 hours for 20 days.
Intracellular protein penetration rate was tested using DyLight labeled ab169901 protein at 1 μg/ ml for 30 min incubation for human fibroblast cells at 37oC. More than 90% cell will be positive one hour after sample incubation.
Purity> 93 % SDS-PAGE.
ab169901 was expressed in E. coli as inclusion bodies, solubilized, refolded, and further purified.
Expression systemEscherichia coli

Additional sequence informationPlease note that ab169901 is isoform 2 of UniProt accession P01106. (NP_002458.2)
Our Abpromise guarantee covers the use of ab169901 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
ab169901 is fused to an eleven arginine (11R) membrane penetration domain at the C terminus to enable penetratation across the plasma membrane of mammalian cells.
Cellular Toxicity: This recombinant protein was tested on mouse embryonic stem cells up to 50 µg/ml in culture medium. Suggested reprogramming protein concentration is between 0.5 to 8 ug / ml for both human and mouse fibroblast cells applications.

- Avian myelocytomatosis viral oncogene homolog
FunctionParticipates in the regulation of gene transcription. Binds DNA in a non-specific manner, yet also specifically recognizes the core sequence 5'-CAC[GA]TG-3'. Seems to activate the transcription of growth-related genes.
Involvement in diseaseNote=Overexpression of MYC is implicated in the etiology of a variety of hematopoietic tumors.
Note=A chromosomal aberration involving MYC may be a cause of a form of B-cell chronic lymphocytic leukemia. Translocation t(8;12)(q24;q22) with BTG1.
Defects in MYC are a cause of Burkitt lymphoma (BL) [MIM:113970]. A form of undifferentiated malignant lymphoma commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. Note=Chromosomal aberrations involving MYC are usually found in Burkitt lymphoma. Translocations t(8;14), t(8;22) or t(2;8) which juxtapose MYC to one of the heavy or light chain immunoglobulin gene loci.
Sequence similaritiesContains 1 basic helix-loop-helix (bHLH) domain.
modificationsPhosphorylated by PRKDC. Phosphorylation at Thr-58 and Ser-62 by GSK3 is required for ubiquitination and degradation by the proteasome.
Ubiquitinated by the SCF(FBXW7) complex when phosphorylated at Thr-58 and Ser-62, leading to its degradation by the proteasome. In the nucleoplasm, ubiquitination is counteracted by USP28, which interacts with isoform 1 of FBXW7 (FBW7alpha), leading to its deubiquitination and preventing degradation. In the nucleolus, however, ubiquitination is not counteracted by USP28, due to the lack of interaction between isoform 4 of FBXW7 (FBW7gamma) and USP28, explaining the selective MYC degradation in the nucleolus. Also polyubiquitinated by the DCX(TRUSS) complex.
Cellular localizationNucleus > nucleoplasm. Nucleus > nucleolus.
