The function of importin β1 is conserved in eukaryotes but the substrates may vary in organisms.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Importin β1 is the nuclear-cytoplasmic transport receptor in eukaryotic cells. Its main function is to transport NLS (nuclear localization signal)-containing proteins from cytoplasm to nucleus. Our recent study found that AtKPNB1, a homolog of the human KPNB1, is an essential component of the classical nuclear import of the NLS-containing proteins in Arabidopsis and modulates plant development and ABA-mediated stress response. Human KPNB1 can also directly transport the nuclear proteins, such as ribosomal protein RPS7e, without the intervention of importin α proteins. However, we found that AtKPNB1 does not directly recognize and import the human RPS7e homologous proteins AtRPS7A, AtRPS7B and AtRPS7C into the nucleus like human KPNB1. These findings suggest that the importin β1 protein has the conserved function in translocating nuclear proteins to the nucleus, but their specific cargos may vary in different organisms.
