Figure 3 .

Putative E3s whose proteins were detected in one or more germ cell types using the iTRAQ mass spectrometry and their corresponding RNA levels detected by RNA-seq data. The protein and RNA expression data of these putative E3s were from two independent studies aiming to examine global gene expression at the mRNA and protein levels. Note most putative E3s were expressed at or after meiosis. The mRNA expression either matches or precedes their protein expression. SG-A: type A spermatogonia, pacSC: pachytene spermatocyte, rST: round spermatid, eST: elonged spermatid.
