Sodium-hydrogen exchanger as a channel for regulation of intracellular pH might be a crucial modulator of sperm capacitation and motility. Three members of this family have been identified in spermatozoa. A novel protein testis-specific sodium-hydrogen exchanger named mtsNHE was cloned in the present study. The mtsNHE localizing on principle piece of sperm flagellum contained 12 predicted trans...
Since plants retain genomes of an extremely large size in mitochondria (200-2,400 kb), and mitochondrial protein complexes are comprised of chimeric structures of nuclear- and mitochondrial-encoded subunits, coordination of gene expression between the nuclei and mitochondria is indispensable for sound plant development. It has been well documented that the nucleus regulates organelle gene expre...
