High impact information on CDY2B

  • Here, we characterize the CDY-related mammalian gene family, focusing on three aspects of its evolution: gene copy number, tissue expression profile and amino acid sequence [1].
  • However, in consideration of the high levels of identity between CDY1 and CDY2 (98% at the protein level), the delayed up-regulation of CDY1 transcripts could be attributable to temporal changes in dosage requirements [2].
  • It is suggested that CDY2 is apparently required in the early stages of spermatogenesis, whereas CDY1 transcripts are required later on in the process [2].
  • CDY2 was expressed whenever germ cells were present, but CDY1 major and especially CDY1 minor and short transcripts were identified almost exclusively when mature spermatids/spermatozoa were detected [2].
