Comments concerning this interaction

Knockdown of Nap1 increases the interaction of mts with SA.

(Moshkin et al., 2013)

Treatment of cells with colchicine arrests cells in mitosis, and decreases the interaction of mts with SA.

(Moshkin et al., 2013)

Source was cell extract of S2 cell line; bait produced from endogenous gene; prey produced from endogenous gene.
