Karyopherins play the field [PDF]

open access: yesThe Journal of Cell Biology, 2006
![][1] Import of proteins (green) into the nucleus is slower than expected, revealing that karyopherins are choosy about their cargo. Proteins that shuttle molecules into the nucleus face the same problem as customers of a dating service.

Karyopherin α 3 and Karyopherin α 4 Proteins Mediate the Nuclear Import of Methyl-CpG Binding Protein 2 [PDF]

open access: yesJournal of Biological Chemistry, 2015
Methyl-CpG binding protein 2 (MeCP2) is a nuclear protein with important roles in regulating chromatin structure and gene expression, and mutations in MECP2 cause Rett syndrome (RTT). Within the MeCP2 protein sequence, the nuclear localization signal (NLS) is reported to reside between amino acids 255-271, and certain RTT-causing mutations overlap with

Effect of transient scrotal hyperthermia on sperm parameters, seminal plasma biochemical markers, and oxidative stress in men

open access: yesAsian Journal of Andrology, 2015
In this experimental prospective study, we aimed to analyze the effect of transient scrotal hyperthermia on the male reproductive organs, from the perspective of sperm parameters, semen plasma biochemical markers, and oxidative stress, to evaluate ...

The paternal genome and the health of the assisted reproductive technology child

open access: yesAsian Journal of Andrology, 2015
As a number of children born by assisted reproductive technology (ART) are increasing each year across the developed world, the health of such offspring is a matter of public concern.

Redox regulation of mammalian sperm capacitation

open access: yesAsian Journal of Andrology, 2015
Capacitation is a series of morphological and metabolic changes necessary for the spermatozoon to achieve fertilizing ability. One of the earlier happenings during mammalian sperm capacitation is the production of reactive oxygen species (ROS) that will ...

ROS-mediated DJ-1 monomerization modulates intracellular trafficking involving Karyopherin-2

open access: yes, 2014
Mutations in DJ-1 are a cause of recessive, early-onset Parkinson's disease (PD). Although oxidative stress and mitochondrial integrity have been implicated in PD, it is largely unknown why neurons degenerate.

Karyopherins in the Remodeling of Extracellular Matrix: Implications in Tendon Injury

open access: yesJournal of Orthopaedics and Sports Medicine, 2023
Rotator Cuff Tendinopathies (RCT) are debilitating conditions characterized by alterations in the extracellular matrix (ECM) of the shoulder tendon, resulting in pain, discomfort, and functional limitations. Specific mediators, including HIF-1α, TGF-β, MMP-9 and others have been implicated in the morphological changes observed in the tendon ECM.

Behavioral mechanisms of mammalian sperm guidance

open access: yesAsian Journal of Andrology, 2015
In mammals, sperm guidance in the oviduct appears essential for successful sperm arrival at the oocyte. Hitherto, three different potential sperm guidance mechanisms have been recognized: thermotaxis, rheotaxis, and chemotaxis, each of them using ...

Dissecting in vivo steady-state dynamics of karyopherin-dependent nuclear transport [PDF]

open access: yes, 2016
Karyopherin-dependent molecular transport through the nuclear pore complex is maintained by constant recycling pathways of karyopherins coupled with the Ran-dependent cargo catch-and-release mechanism.

The role of the molecular chaperone heat shock protein A2 (HSPA2) in regulating human sperm-egg recognition

open access: yesAsian Journal of Andrology, 2015
One of the most common lesions present in the spermatozoa of human infertility patients is an idiopathic failure of sperm-egg recognition. Although this unique cellular interaction can now be readily by-passed by assisted reproductive strategies such as ...
