CRYSTAL STRUCTURE ANALYSIS OF KINASE ASSOCIATED PHOSPHATASE (KAP) WITH A SUBSTITUTION OF THE CATALYTIC SITE CYSTEINE (CYS140) TO A SERINE

Template:ABSTRACT PUBMED 11463386

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]

About this Structure
