Background:

This gene encodes one member of a family of translation repressor proteins. The protein directly interacts with eukaryotic translation initiation factor 4E, which is a
limiting component of the multisubunit complex that recruits 40S ribosomal subunits to the 5′ end of mRNAs. Interaction of this protein with 4E inhibits complex assembly
and represses translation. This protein is phosphorylated in response to various signals including UV irradiation and insulin signaling, resulting in its dissociation from 4E and activation of mRNA translation.

Form: liquid
Buffer: PBS with 0.02% sodium azide,50% glycerol,pH7.3.
