1bd8 Summary



The structure was published by Baumgartner, R., Fernandez-Catalan, C., Winoto, A., Huber, R., Engh, R.A., and Holak, T.A., in 1998 in a paper entitled "Structure of human cyclin-dependent kinase inhibitor p19INK4d: comparison to known ankyrin-repeat-containing structures and implications for the dysfunction of tumor suppressor p16INK4a." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of P19INK4D CDK4/6 INHIBITOR. This molecule has the UniProt identifier P55273 (CDN2D_HUMAN)search. The sample contained 156 residues which is 94% of the natural sequence. Out of 156 residues 156 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
