Importin α transports CaMKIV to the nucleus without utilizing importin β [PDF]
Ca(2+)/calmodulin-dependent protein kinase type IV (CaMKIV) plays an essential role in the transcriptional activation of cAMP response element-binding protein-mediated signaling pathways. Although CaMKIV is localized predominantly in the nucleus, the molecular mechanism of the nuclear import of CaMKIV has not been elucidated.

Probing formation of cargo/importin-α transport complexes in plant cells using a pathogen effector [PDF]
Importin-αs are essential adapter proteins that recruit cytoplasmic proteins destined for active nuclear import to the nuclear transport machinery. Cargo proteins interact with the importin-α armadillo repeat domain via nuclear localization sequences ...

UV-induced nuclear import of XPA is mediated by importin-α4 in an ATR-dependent manner. [PDF]
Xeroderma pigmentosum Group A (XPA) is a crucial factor in mammalian nucleotide excision repair (NER) and nuclear import of XPA from the cytoplasm for NER is regulated in cellular DNA damage responses in S-phase.

Phosphorylation of importin-α1 by CDK1-cyclin B1 controls mitotic spindle assembly [PDF]
Importin-α serves as an adaptor linking importin-β to proteins carrying a nuclear localization sequence (NLS). During interphase, this interaction enables nuclear protein import, while in mitosis it regulates spindle assembly factors (SAFs) and controls ...

Karyopherin α7 (KPNA7), a divergent member of the importin α family of nuclear import receptors
Background Classical nuclear localization signal (NLS) dependent nuclear import is carried out by a heterodimer of importin α and importin β. NLS cargo is recognized by importin α, which is bound by importin β.
