Abstract: Eukaryotic translation initiation factor 2 subunit 3 and structural gene Y-linked
(Eif2s3y) gene, the gene encoding eIF2γ protein, is located on the mouse Y chromosome short arm.
The Eif2s3y gene is globally expressed in all tissues and plays an important role in regulating global
and gene-specific mRNA translation initiation. During the process of protein translation initiation,
Eif2s3x (its homolog) and Eif2s3y encoded eIF2γ perform similar functions. However, it has
been noticed that Eif2s3y plays a crucial role in spermatogenesis, including spermatogonia mitosis,
meiosis, and spermiogenesis of spermatids, which may account for infertility. In the period of spermatogenesis,
the role of Eif2s3x and Eif2s3y are not equivalent. Importance of Eif2s3y has been observed
in ESC and implicated in several aspects, including the pluripotency state and the proliferation
rate. Here, we discuss the functional significance of Eif2s3y in mouse spermatogenesis and
self-renewal of ESCs.
