TMT-based proteomics analysis of mouse germ cells


ABSTRACT: The proteome changes were quantified in RibosomeRPL39L-/- spermatocytes and elongated spermatids using TMT 6-plex, and in spermatogonia, spermatocytes, round spermatids and elongated spermatids using TMT 10-plex by LC-MS/MS.

Ribosomes are highly sophisticated translation machines that have been demonstrated to be heterogeneous in the regulation of protein synthesis<sup>1,2</sup>. Male germ cell development involves complex translational regulation during sperm formation<sup>3</sup>. However, it remains unclear whether translation during sperm formation is performed by a specific ribosome. Here we report a ribosome with a specialized nascent polypeptide exit tunnel, Ribosome<sup>ST</sup>, that is assembled with the m  ...[more]
