SOLUTION NMR STRUCTURE OF TUMOR SUPPRESSOR P16INK4A, 18 STRUCTURES

The structure was published by Byeon, I.J., Li, J., Ericson, K., et al., Kim, H.J., O'Maille, P., and Tsai, M.D., in 1998 in a paper entitled "Tumor suppressor p16INK4A: determination of solution structure and analyses of its interaction with cyclin-dependent kinase 4." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1998.

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

The PDB entry contains the structure of TUMOR SUPPRESSOR 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.
