MDM4
From Proteopedia
Contents |
Function
MDM4 is a 490 amino acid protein containing a RING finger domain (residues 300-339) and a nuclear localization signal. MDM4 interacts with protein MDM2[1]. Both of these proteins show structure similarity and contain a p53-binding domain (or SWIB domain) in their N terminal (residues 23-111).
Relevance
MDM4 which is a negative regulator of p53 is upregulated in human melanomas and thus is a key therapeutic target[2].
