Two type I DnaJ homologs DjA1 (DNAJA1; dj2, HSDJ/hdj-2, rdj1) and DjA2 (DNAJA2; dj3, rdj2) work similarly as a cochaperone of Hsp70s in protein folding and mitochondrial protein import in vitro. To study the in vivo role of DjA1, we generated DjA1-mutant mice. Surprisingly, loss of DjA1 in mice led to severe defects in spermatogenesis that involve aberrant androgen signaling. Transplantation ex...
T-007 is a Male Recombination (MR) second chromosome that induces transmission ratio distortion (at its own expense) when heterozygous with many laboratory marker chromosomes. The developmental timing of elimination of T-007 chromosomes has been investigated. About 21% of the T-007 chromosomes expected to be recovered among the progeny of heterozygous T-007 males are lost at some point between ...
Spermiogenesis is a series of poorly understood morphological, physiological and biochemical processes that occur during the transition of immotile spermatids into motile, fertilization-competent spermatozoa. Here, we identified a Serpin (serine protease inhibitor) family protein (As_SRP-1) that is secreted from spermatids during nematode Ascaris suum spermiogenesis (also called sperm activatio...
