Human sperm chromatin epigenetic potential: genomics, proteomics, and male infertility
The classical idea about the function of the mammalian sperm chromatin is that it serves to transmit a highly protected and transcriptionally inactive paternal genome, largely condensed by protamines, to the next generation.

Background Karyopherin α-2 (KPNA2) is a member of karyopherin family, which is proved to be responsible for the import or export of cargo proteins. Studies have determined that KPNA2 is associated with the development and prognosis of various cancers ...

New insights into the regulation of cholesterol efflux from the sperm membrane
Cholesterol is an essential component of the mammalian plasma membrane because it promotes membrane stability without comprising membrane fluidity. Given this important cellular role, cholesterol levels are tightly controlled at multiple levels.

The genetic basis of preimplantation embryo arrest is slowly being unraveled. Recent discoveries point to maternally expressed proteins required for cellular functions before the embryonic genome is activated. In this issue of the JCI, Wang, Miyamoto, et

A 3D Physical Model of Karyopherin‐β2
Karyopherin beta 2 (Kapβ2) is an importin that transports various cargo proteins into the nucleus through interactions with nucleoporins, which are proteins of the nuclear pore complex (NPC). One might overlook the significance of this protein but it actually plays a crucial role in the human body.

Previously identified protein of uncertain function is karyopherin alpha and together with karyopherin beta docks import substrate at nuclear pore complexes. [PDF]
Previously, we had purified a cytosolic protein complex, termed karyopherin, that functions in docking import substrate at the nuclear envelope in digitonin-permeabilized cells and also had molecularly cloned and sequenced its 97-kDa beta subunit. We now report that the karyopherin alpha subunit is the previously identified protein NPI-1/SRP-1 of ...

Nuclear Transport of Yeast Proteasomes
Proteasomes are key proteases in regulating protein homeostasis. Their holo-enzymes are composed of 40 different subunits which are arranged in a proteolytic core (CP) flanked by one to two regulatory particles (RP).

Structural Insights Into the Nuclear Import of Marek’s Disease Virus Large Tegument Protein
Marek’s disease (MD) is a highly contagious neoplastic disorder of poultry caused by MD virus (MDV; gallid alphaherpesvirus 2 [GaAHV2]). Infection results in profound immunosuppression, neurological dysfunction, and the development of malignant T‐cell lymphomas.
