Tob1 is expressed in developing and adult gonads and is associated with the P-body marker, Dcp2

Abstract

Tob1 is a member of the BTG/TOB family of proteins with established antiproliferative function. In Danio rerio and Xenopus laevis, the Tob1 gene is expressed from the one-cell stage through to early gastrula stages, followed in later development by discrete expression in many tissues including the notochord and somites. In both mouse and human, Tob1 is expressed in many adult tissues including the testis and ovary; however, the specific cell types are unknown. We examine Tob1 gene expression in mouse in developing germ cells and in sorted male germ cells (gonocytes, spermatogonia, pachytene spermatocytes and round spermatids) by reverse transcription and droplet digital polymerase chain reac..
