Karyopherin Alpha Proteins Regulate Oligodendrocyte Differentiation. [PDF]
Proper regulation of the coordinated transcriptional program that drives oligodendrocyte (OL) differentiation is essential for central nervous system myelin formation and repair.

Multi-omics analysis identifies a major histocompatibility complex class II-associated antigen-presenting cancer-associated fibroblast-like state linked to the nuclear factor erythroid 2-related factor 2-karyopherin subunit beta 1 axis in nonsmall cell lung cancer. [PDF]
NSCLC contains an MHC‐II‐associated antigen‐presenting CAF‐like (apCAF‐like) state regulated by the NRF2‐KPNB1 axis. NRF2/KPNB1 signaling suppresses CIITA‐dependent antigen presentation and T‐cell activation, whereas inhibition of this pathway enhances antitumor immunity and improves responsiveness to anti‐PD‐1 therapy.

Karyopherin α deficiency contributes to human preimplantation embryo arrest
Preimplantation embryo arrest (PREMBA) is a common cause of female infertility and recurrent failure of assisted reproductive technology. However, the genetic basis of PREMBA is largely unrevealed.

Several aggregation-prone RNA-binding proteins, including FUS, EWS, TAF15, hnRNP A1, hnRNP A2, and TDP-43, are mutated in neurodegenerative diseases. The nuclear-cytoplasmic distribution of these proteins is controlled by proteins in the karyopherin family of nuclear transport factors (Kaps). Recent studies have shown that Kaps not only transport these

A Role for the Karyopherin Kap123p in Microtubule Stability [PDF]
Several components of the nuclear transport machinery play a role in mitotic spindle assembly in higher eukaryotes. To further investigate the role of this family of proteins in microtubule function, we screened for mutations in Saccharomyces cerevisiae that confer sensitivity to microtubule‐destabilizing drugs.

The role of karyopherins in the regulated sumoylation of septins [PDF]
In the yeast Saccharomyces cerevisiae, several components of the septin ring are sumoylated during anaphase and then abruptly desumoylated at cytokinesis. We show that septin sumoylation is controlled by the interactions of two enzymes of the sumoylation pathway, Siz1p and Ulp1p, with the nuclear transport machinery.

Malfunction of nuclear-cytoplasmic transport contributes to many diseases including cancer. Defective nuclear transport leads to changes in both the physiological levels and temporal-spatial location of tumor suppressors, proto-oncogenes and other macromolecules that in turn affect the tumorigenesis process and drug sensitivity of cancer cells.

Modulation of Histone Deposition by the Karyopherin Kap114 [PDF]
The nuclear import of histones is a prerequisite for the downstream deposition of histones to form chromatin. However, the coordinate regulation of these processes remains poorly understood. Here we demonstrate that Kap114p, the primary karyopherin/importin responsible for the nuclear import of histones H2A and H2B, modulates the deposition of histones

The binding site of karyopherin alpha for karyopherin beta overlaps with a nuclear localization sequence. [PDF]
By using proteolysis, recombinant mutant proteins, or synthetic peptides and by testing these reagents in liquid phase binding or nuclear import assays, we have mapped binding regions of karyopherin alpha. We found that the C-terminal region of karyopherin alpha recognizes the nuclear localization sequence (NLS), whereas its N-terminal region binds ...

<b><i>Introduction:</i></b> Karyopherin alpha 2 (KPNA2) and karyopherin beta 1 (KPNB1) constitute nuclear transport protein complexes involved in nuclear import and are significant in tumor progression. Although high KPNA2 expression was associated with poor prognosis in solid tumors, the relationship between KPNA2 and KPNB1 ...
