SUN and KASH proteins embedded in the nuclear envelope provide connections between the organization of the nucleus and the cytoplasm. Which of the following pairs of proteins DO NOT bind directly to each other in these connections?
A) Nuclear lamina and SUN proteins
B) Plectins and KASH proteins
C) KASH proteins and microfilaments
D) KASH proteins and SUN proteins
E) SUN proteins and cytoplasmic intermediate filaments.

Question

Quizplus · Accepted Answer

SUN proteins in the inner nuclear membrane bind to KASH proteins in the outer nuclear membranes. Through this interaction, nuclear lamina and chromosomes (which bind to SUN proteins) are connected to actin filaments, microtubule motors, or plectins (which bind to KASH proteins) in the cytoplasm.
