Figure Lengend Snippet: Fig. 1. Characterization of SUN2-AS1. (A) A schematic representation of human SUN2-AS1 transcribed from the antisense strand of the protein-coding gene SUN2 on chromosome 22. (B) 5′- and 3′ RACE was conducted to determine the full length of SUN2-AS1. Full-length SUN2-AS1 was chemically synthesized and cloned into the pcDNA3.1(+) vector. Total RNA from ZIKV-infected A549 cells was extracted at 24 h.p.i. The RNA was then reverse transcribed and amplified using the SMARTer RACE cDNA amplification kit. (C) The CPAT (Coding Potential Assessment Tool) was used to predict the coding probability of SUN2-AS1. (D) 293T cells were transfected with pcDNA3.1-GFP-HA (vector control), SUN2-HA (positive control), pcDNA3.1-HA-SUN2-AS1, or pcDNA3.1-SUN2-AS1-HA plasmid. At 36 h post- transfection, cells were harvested for a Western blot analysis to detect anti-HA bands. Blots were representative of at three independent experiments. (E) The relative expression of human β-actin (cytoplasmic control), U6 (nuclear control), and the expression of SUN2-AS1 were analyzed by using qRT-PCR in the nuclear and cytoplasmic fractions.

Article Title: The SUN2-nesprin-2 LINC complex and KIF20A function in the Golgi dispersal.

doi: 10.1038/s41598-021-84750-4

Figure Lengend Snippet: Figure 6. Working model for the regulation of the Golgi organization by LINC complex. Left, The minus-end- directed MT motor activity, i.e., dynein (blue), dominates plus-end-directed motor activity under a steady-state condition, and juxtanuclear accumulation of the Golgi complex is observed. Right, In SUN1-depleted cells, KIF20A is activated or suppression of KIF20A activity is cancelled, and KIF20A activity dominates dynein activity. An explanation for the inhibition of KIF20A activity in the presence of SUN1 is that LINC complex formations are biased towards SUN1 inclusion and SUN2/nesprin-2 LINC complex formation is suppressed. In response to SUN1 depletion, incorporation of nesprin-2 in the SUN1-LINC complex decreased and SUN2/ nesprin-2 LINC complexes are formed. As a result, functions of KIF20A acting with a SUN2/nesprin-2 LINC complex becomes predominant (orange) over the minus-end-directed motor activities (blue), and the Golgi complex is dispersed.
