SOLUTION NMR STRUCTURE OF TUMOR SUPPRESSOR P16INK4A, 20 STRUCTURES

The structure was published by Yuan, C., Selby, T.L., Li, J., Byeon, I.J., and Tsai, M.D., in 2000 in a paper entitled "Tumor suppressor INK4: refinement of p16INK4A structure and determination of p15INK4B structure by comparative modeling and NMR data." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1999.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of CYCLIN-DEPENDENT KINASE 4 INHIBITOR A (P16INK4A). This molecule has the UniProt identifier P42771 (CD2A1_HUMAN)search. The sample contained 156 residues which is 100% of the natural sequence. Out of 156 residues 156 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
