Structural highlights

1fpz is a 6 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:	Protein-tyrosine-phosphatase, with EC number 3.1.3.48
Resources:	FirstGlance, OCA, RCSB, PDBsum

Disease

[CDKN3_HUMAN] Defects in CDKN3 are found in patients with hepatocellular carcinoma (HCC) [MIM:114550].^[1]

Function

[CDKN3_HUMAN] May play a role in cell cycle regulation. Dual specificity phosphatase active toward substrates containing either phosphotyrosine or phosphoserine residues. Dephosphorylates CDK2 at 'Thr-160' in a cyclin-dependent manner.^[2] ^[3] ^[4]

Publication Abstract from PubMed

The CDK-interacting protein phosphatase KAP dephosphorylates phosphoThr-160 (pThr-160) of the CDK2 activation segment, the site of regulatory phosphorylation that is essential for kinase activity. Here we describe the crystal structure of KAP in association with pThr-160-CDK2, representing an example of a protein phosphatase in complex with its intact protein substrate. The major protein interface between the two molecules is formed by the C-terminal lobe of CDK2 and the C-terminal helix of KAP, regions remote from the kinase-activation segment and the KAP catalytic site. The kinase-activation segment interacts with the catalytic site of KAP almost entirely via the phosphate group of pThr-160. This interaction requires that the activation segment is unfolded and drawn away from the kinase molecule, inducing a conformation of CDK2 similar to the activated state observed in the CDK2/cyclin A complex.

Phosphoprotein-protein interactions revealed by the crystal structure of kinase-associated phosphatase in complex with phosphoCDK2.,Song H, Hanlon N, Brown NR, Noble ME, Johnson LN, Barford D Mol Cell. 2001 Mar;7(3):615-26. PMID:11463386^[5]
