Function

MEX3D is an RNA binding protein that interacts with AU-rich elements of Bcl-2. Upon binding, MEX3D has a negative regulatory action on Bcl-2 expression at the posttranscriptional level.^[6]

Structure

MEX3 proteins contain two N-terminal heterogeneous nuclear ribonucleoprotein K homology motifs (KH domain) and a RING domain at the C-terminus.^[6]
