From: Mining and characterization of ubiquitin E3 ligases expressed in the mouse testis
Expression profiles of E3 genes in different tissues. Expression of different families of E3s were ranked based on their levels in the mouse testis (P for present, HP for highly present, SP for specific). The expression of genes of these three levels were examined in other tissues such as the liver, the lung, and muscle. (A) Almost all the SP-level E3 genes were only expressed in the mouse testes. (B) More HP-level genes were expressed in the testes than in other tissues. (C) Genes that were expressed in the testis (P-level genes) were also expressed in other tissues.
