SSP1 — Verticillium dahliae

Summary

VDAG_07697 (VdSSP1, also known as SSP1, STK-22 or VdSTK-22) in Verticillium dahliae encodes a non-specific serine/threonine protein kinase with Ca2+/calmodulin-dependent kinase activity, calmodulin binding, and ATP binding. It is associated with the CAMKK-AMPK signaling cascade, positive regulation of mitotic entry and cell cycle switching from mitotic to meiotic, and negative regulation of calcineurin-mediated signaling, TORC1 signaling, and cytoplasmic translation. The gene is linked to mitotic cytokinesis site selection, actin cytoskeleton organization and polarity, phospholipid translocation, plasma membrane organization, cellular response to calcium ions and glucose starvation, and cell growth mode switching. VdSSP1 localizes to the cell cortex of growing and non-growing cell tips, the microtubule cytoskeleton, and the mitotic actomyosin contractile ring. It is associated with wilt in Gossypium hirsutum.
