这个基因编码翻译抑制蛋白家族的一个成员。该蛋白直接与真核细胞翻译起始因子4e（eif4e）相互作用，该因子是多亚单位复合物的一个限制性成分，在mRNAs的5'端招募40s核糖体亚单位。这种蛋白与eif4e的相互作用抑制复杂的装配和翻译。这种蛋白被磷酸化，以响应各种信号，包括紫外线辐射和胰岛素信号，导致其与eif4e的分离和激活的mRNA翻译。
This gene encodes one member of a family of translation repressor proteins. The protein directly interacts with eukaryotic translation initiation factor 4E (eIF4E), 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 eIF4E 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 eIF4E and activation of mRNA translation.
