MEX3C

Gene
MEX3C
Protein
RNA-binding E3 ubiquitin-protein ligase MEX3C
Organism
Homo sapiens
Length
659 amino acids
Function
E3 ubiquitin ligase responsible for the post-transcriptional regulation of common HLA-A allotypes. Binds to the 3' UTR of HLA-A2 mRNA, and regulates its levels by promoting mRNA decay. RNA binding is sufficient to prevent translation, but ubiquitin ligase activity is required for mRNA degradation.

Gene
Mex3c
Protein
RNA-binding E3 ubiquitin-protein ligase MEX3C
Organism
Mus musculus
Length
652 amino acids
Function
RNA-binding protein. May be involved in post-transcriptional regulatory mechanisms, modulating levels of some mRNAs by promoting their degradation in a way involving ubiquitin ligase activity. May act as suppressor of replication stress and chromosome missegregation.
