Rescue of failed oocyte activation after ICSI in a mouse model of male factor infertility by recombinant phospholipase Cζ.

abstract：:FAF1 was initially isolated as a Fas-associated factor and was subsequently found to interact with a subset of additional proteins that are involved in many cellular events including Fas-mediated apoptosis, heat shock signalling pathways and ubiquitin-dependent processes. Here, we describe that the 74-kDa FAF1 is ubiq...
